Overview OEM radio modules deRFmega The tiny radio module series by dresden elektronik combines Atmels 8-bit AVR single chip ATmega128RFA1 and ATmega256RFR2 with a small footprint. Six different module types are available providing different features for the custom application. The deRFmega128-22M00 and deRFmega256-23M00 have an onboard chip antenna to establish a ready-to-use device. No additional and expensive RF designs are necessary. This module is full compliant to all EU and US regulatory requirements. The deRFmega128-22M10 and deRFmega256-23M10 have the smallest form factor of all module types. The customer is free to design his own antenna, coaxial output or front-end;

but it is also possible to use one of the dresden elektroniks certified and documented RF designs. The deRFmega128-22M12 and deRFmega256-23M12 have an onboard front-end feature including LNA and PA with 20 dB gain. Furthermore it supports antenna diversity by a direct connection of two antennas or coaxial connectors. All necessary RF parts and switches are integrated. This module type combined with the small form factor is the optimal solution between range extension and space for mounting on PCB. 2. Applications The main applications for the radio modules are:

External front-end and antenna diversity control The radio modules deRFmega128-22M10 and deRFmega256-23M10 offer the possibility to control external front-end components and to support antenna diversity. Table 7-3 and Table 7-4 show the logic values of the control signals. A logic 0 is specified with a voltage level of 0 V to 0.3 V. A logic 1 is specified with a value of VCC - 0.3 V to 3.6 V. An application circuit is shown in Section 10.5. Antenna Diversity The antenna diversity algorithm is enabled with setting bit ANT_DIV_EN=1 in the ANT_DIV register. The external control of RF switches must be enabled by bit ANT_EXT_SW_EN of the same register. This action will configure the pins DIG1 and DIG2 as outputs. Both pins are used to feed the RF switch signal and its inverse to the differential inputs of the RF switch.

PCB design OEM radio modules deRFmega The PCB design of a radio module base board is important for a proper performance of peripherals and the radio. The next subsections give design hints to create a custom base board. 8.1. Technology The described design has the main goal to use standard PCB technology to reduce the costs and cover a wider application range. Design parameters 150 m manufacturing process 4 layer PCB with FR4 Prepreg No via plugging Via hole size: 0.2 mm Via diameter: 0.6 mm 8.2. Base board footprint The footprint for a custom base board depends on the radio module used. The mechanical dimensions are shown in Section 5. The following part describes an example to design a base board. Properties of stencil and solder paste Stencil = 130 m thickness Lead free solder paste (particle size from 20 to 38 m) Properties of signal pads Signal pad dimension = 0.6 x 0.6 mm (rectangular, red) Signal pad cut-out on stencil = 0.6 x 0.6 mm (rectangular, grey) Clearance to solder stop = 0.1 mm (purple) Figure 31: Signal pad footprint design Properties of RF pads RF ground pad dimension = 1.6 x 0.5 mm (round, red) RF ground pad cut-out on stencil = 1.3 x 0.2 mm (round, grey) RF signal-out pad dimension = 0.6 x 0.6 mm (round, red) RF signal-out pad cut-out on stencil = 0.6 x 0.6 mm (round, grey) Clearance to solder stop = 0.1 mm (purple) www.dresden-elektronik.de Page 41 of 69 User Manual Version 1.3 2013-06-10 OEM radio modules deRFmega Figure 32: RF pad footprint design (top view) 8.2.1. Footprint of deRFmega128-22M00 and deRFmega256-23M00 Figure 33 shows an exemplary base board footprint for deRFmega128-22M00 and deRFmega256-23M00. Only the top layer (red) is visible. The mid and bottom layers are hidden. The rectangular signal pad copper area (red, not visible) and the paste dimension

(grey) have the same size of 0.6 x 0.6 mm. The solder stop clearance (purple) has a value of 0.1 mm. Do not place copper on any other area among the entire module. Solder stop could be used everywhere. Figure 33: Exemplary base board footprint for 22M00 / 23M00 (top view) www.dresden-elektronik.de Page 42 of 69 User Manual Version 1.3 2013-06-10 OEM radio modules deRFmega 8.2.2. Footprint of deRFmega128-22M10 and deRfmega256-23M10 The exemplary base board footprint for deRFmega128-22M10 and deRFmega256-23M10 is shown in Figure 34. The top layer (red) is visible, the mid and bottom layers are hidden. The rectangular signal pad copper area (red, not visible) and the paste dimension (grey) have the same size of 0.6 x 0.6 mm. The solder stop clearance (purple) has a value of 0.1 mm. The RF ground pads are connected to each other and to the board ground to ensure a proper ground area. For the most applications it is not necessary to separate the RF ground from system ground. The RF ground area in Figure 34 has a vertical dimension of 3.8 mm. The ground vias are not plugged. In this area are no other radio module signals. An unintentional short-circuit is therefore accepted. Do not place copper on any other area among the entire module. Solder stop could be used everywhere. The RF trace design depends on the used base board and is described detailed in Section 8.5.

Footprint of deRFmega128-22M12 and deRFmega256-23M12 Figure 35 shows an exemplary base board footprint for deRFmega128-22M12 and deRFmega256-23M12. Only the top layer (red) is visible. The mid and bottom layers are hidden. The pad copper area (red, not visible) and the paste dimension (grey) have the same size of 0.6 x 0.6 mm. The solder stop clearance (purple) has a value of 0.1 mm. The RF ground pads are connected to each other and to the board ground to ensure a proper ground area. For the most applications it is not necessary to separate the RF ground from system ground. The RF ground area in Figure 35 has a vertical dimension of 9.4 mm. The ground vias are not plugged. In this area are no other radio module signals. An unintentional short-circuit is therefore accepted. Do not place copper on any other area among the entire module. Solder stop could be used everywhere. The RF trace design depends on the used base board and is described detailed Section 8.5. Figure 35: Exemplary base board footprint for 22M12 / 23M12 (top view) 8.3. Ground plane The performance of RF applications mainly depends on the ground plane design. The often used chip ceramic antennas are very tiny, but they need a proper ground plane to establish a good radiation pattern. Every board design is different and cannot easily be compared to each other. Some practical notes for the ground plane design are described below:

Regard to the design guideline of the antenna manufacturer Use closed ground planes on the PCB edges on top and bottom layer Connect the ground planes with lots of vias. Place it inside the PCB like a chessboard and on the edges very closely. www.dresden-elektronik.de Page 44 of 69 User Manual Version 1.3 2013-06-10 8.4. Layers OEM radio modules deRFmega The use of 2 or 4 layer boards have advantages and disadvantages for the design of a custom base board. Table 8-1: 2 and 4 layer board properties in comparison 2 Layer board 4 Layer board

Traces OEM radio modules deRFmega Common signal traces should be designed with these guidelines:

Traces on top layer are not allowed under the module (see Figure 36) Traces on mid layers and bottom layers are allowed (see Figure 36) Route traces straight away from module (see Figure 33) Do not use heat traps of components directly on the RF trace Do not use 90 degree corners. Better is 45 degree or rounded corners. The trace design for RF signals has a lot of more important points to regard. It defines the trace impedance and therefore the signal reflection and transmission. The most commonly used RF trace designs are Microstrip and Grounded Coplanar Wave Guide (GCPW). The dimension of the trace is depending on the used PCB material, the height of the material to the next ground plane, a PCB with or without a ground plane, the trace width and for GCPW the gap to the top ground plane. The calculation is not trivial, therefore specific literature and web content is available (see [3]) The reference plane to the GCPW should always be a ground area, that means the bottom layer for a 2 layer design and mid layer 1 for a 4 layer design (see Figure 37). Furthermore, it is important to use a PCB material with a known layer stack and relative permittivity. Small differences in the material thickness have a great influence on the trace impedance, especially on 4 layer designs.

Placement on the PCB The PCB design of the radio module base board and placement affects the radio characteristic. The radio module with chip antenna should be placed at the edge or side of a base board. The chip antenna should be directed to PCB side. Figure 38: Placing at the edge Figure 39: Placing at the center edge Do not place the chip antenna radio module within the base board. This will effect a very poor radio performance. Instead radio modules with RF pads could be placed everywhere on the PCB. But it should be enough space for routing a RF trace to a coaxial connector or to an onboard antenna. Figure 40: Placing in the center with antenna Figure 41: Placing in the center with RF pad Do not place ground areas below the radio module (see Section 8.4) and near the chip antenna. Figure 42: No ground plane under the module www.dresden-elektronik.de Page 47 of 69 User Manual Version 1.3 2013-06-10 OEM radio modules deRFmega 8.7. Reference Design for deRFmega256-23M12 8.7.1. Overview for a fast design-in of radio modules. Following A reference design allows its recommendations the most RF issues become subsidiary. Even with less or no RF experience it will be possible to get an optimal RF performance of a custom design. This reference design description must be respected for the use of deRFmega256-23M12 in the United States and to fulfil the requirements of FCC regulations according to the Transmitter Module Equipment Authorization Guide [10]. See chapter 14.1 for further notes of FCC compliance. If the reference design will be integrated into a custom design, it will fulfil the FCC requirements too. The radio module deRFmega256-23M12 was measured and certified on the reference design board named RaspBee (see Figure 43). Further information on this device can be found in chapter 16. All following design descriptions are based on RaspBee. Figure 43: Reference design board (RaspBee) The design guide allows it to create a base board according to the reference board PCB properties. To fulfil the above-mentioned FCC requirements, the RF area of a custom PCB must have the same (design) properties. Any deviation from the reference design will result in a loss of FCC certification of the radio module and the custom design, unless the individual design will be certified again. However re-certification is possible and may be performed as Permissive Change Class II [11]. A partial re-measurement of RF properties is necessary. Note:

Please get in contact with us to advise you for a custom FCC certified design. If necessary we will also provide RF part design data.. This may require signing a Non-

Disclosure Agreement. The important area of the reference design is the RF part shown in Figure 44. One RF-OUT pad of the radio module is connected to the chip-antenna and the other RF-OUT pad is connected to a coaxial connector or an optional wire-antenna. It is also permitted to use only one of the both RF outputs, if needed. In this case terminate the unused port with 50ohms to ground. www.dresden-elektronik.de Page 48 of 69 User Manual Version 1.3 2013-06-10 Figure 44: RF design OEM radio modules deRFmega 8.7.2. PCB design The used standard technology PCB has the following properties:

two-layer board board material FR4 TG 135 dielectric constant 4.4 to 4.8 at 1 MHz board thickness of 1.55mm copper layer thickness of 35m no silk screen used top and bottom solder If the custom board is a multi-layer board, it is possible to leave blank all inner layers within the RF part to get a two-layer board in this area. Figure 45 shows the layer stack as presented by the PCB design tool. Figure 45: PCB Layer stack 8.7.3. RF trace design The RF trace is designed as GCPW (see chapter 8.5) with the following properties:

GCPW width is 0.7mm GCPW gap is 0.2mm www.dresden-elektronik.de Page 49 of 69 User Manual Version 1.3 2013-06-10 OEM radio modules deRFmega Figure 46 shows the RF traces including their length. The middle traces and matching parts are routed in a 45 degree pitch. The PCB design tool defines a traces as a line with a specified width. However the traces have a round edge unlike the measurement start and end point. If one of the RF traces will not be used, it is necessary to terminate it with 50 ohms to ground. A 49.9 ohms 0402 resistor is applicable. Figure 46: RF trace length All matching parts are shown in Figure 44 and have a 0402 footprint with these dimensions:

Pad width is 0.5mm Pad length is 0.6mm Pad center to center distance is 1.1mm Figure 47: Pad design 0402 www.dresden-elektronik.de Page 50 of 69 User Manual Version 1.3 2013-06-10 8.7.4.

Ground area and vias The ground area is important to ensure a proper RF radiation and antenna characteristic. Both ground planes on top and bottom layer (highlighted in Figure 50 and Figure 51) must be connected together with sufficient vias. The ground planes should not be separated by other signal traces. Figure 50: Top ground Figure 51: Bottom ground www.dresden-elektronik.de Page 53 of 69 User Manual Version 1.3 2013-06-10 9. Clock OEM radio modules deRFmega The radio module contains an onboard 32.768 kHz 20 ppm quartz crystal for the MCU and a 16.000 MHz 10 ppm quartz crystal for the internal transceiver. For optimum RF timing characteristics it is necessary to use a low tolerance crystal. The watch crystal clocks a timer, not the processor. The timer is intended to wake-up the processor periodically. www.dresden-elektronik.de Page 54 of 69 User Manual Version 1.3 2013-06-10 OEM radio modules deRFmega 10. Application circuits 10.1. UART Two U(S)ART interfaces are available on the radio modules. For communication to a host with a different supply voltage domain it is necessary to use a level-shifter. We recommend the USB level shifter by dresden elektronik. The level-shifter can be connected to the custom base board via 100 mil 2 x 3 pin header. The pin assignment should be designed as below in Figure 52. For an UART connection it is sufficient to use only TXD, RXD and GROUND signals. 1. PE1/TXD0 2. VCC 3. Not connected 4. PE0/RXD0 5. Not connected 6. GND Figure 52: 100 mil 2 x 3 pin header for UART0 10.2. ISP The AVR based radio modules can be programmed via JTAG and ISP interface. For ISP connections a 100 mil 2 x 3 pin header should be used. The pin assignment is given in Figure 53. The MCU ATmega128RFA1 uses the ISP signals PDO and PDI on the same pins like the SPI with MISO and MOSI. We recommend the use of an AVR ISP programmer. 1. PB3/MISO/PDO 2. VCC 3. PB1/SCK 4.

TWI OEM radio modules deRFmega The connection of external peripherals or sensors via Two-Wire-Interface is possible by using the TWI clock signal PD0/SCL and TWI data signal PD1/SCA. The necessary pull-up resistors must be placed externally on the base board. We recommend the use of 4.7 k resistors as shown in Figure 55. Figure 55: Two-Wire-Interface www.dresden-elektronik.de Page 56 of 69 User Manual Version 1.3 2013-06-10 OEM radio modules deRFmega 10.5. External front-end and antenna diversity The radio module deRFmega128-22M10 and deRFmega256-23M10 can be connected with an external front-end including power amplifier (PA) for transmission and low noise block

(LNA) for receiving. Figure 56 shows a possible design as block diagram. A custom design can contain a single PA or single LNA or a complete integrated front-end chip. It depends mainly on the application. Furthermore, it is possible to include a RF switch for driving the antenna diversity feature. Figure 56: block diagram for external PA/LNA and antenna diversity control Unbalanced RF output The radio module 22M10 has a 50 unbalanced RF output. For designs with external RF power amplifier a RF switch is required to separate the TX and RX path. RF switches to PA, LNA and antenna The switch must have 50 inputs and outputs for the RF signal. The switch control could be realized with the DIG3 and DIG4 signal of the radio module. Refer to Section 7.2.1 for detailed information. PA The PA has to be placed on the TX path after the RF switch. It is important to regard the PAs manufacturer datasheet and application notes, especially for designing the power supply and ground areas. A poor design could cause a very poor RF performance. For energy efficiency it is useful to activate the PA only during TX signal transmission. In this case the DIG3 signal can be used as switch for (de-)activating the PA. Some PAs have the possibility to set them into sleep state. This application can be realized via a dedicated GPIO pin. Refer to Section 7.2.1 for more information. BPF The use of a band-pass filter is optional. It depends on the PA properties. Some PAs have an internal BPF and other do not have. The BPF is necessary to suppress spurious emissions of the harmonics and to be compliant with national EMI limits. It is possible to use an integrated BPF part or discrete parts. The advantage of the first variant is that the BPF characteristic is known and published in the manufacturers datasheet. www.dresden-elektronik.de Page 57 of 69 deRFmega12822M10VCC1.8V to 3.6VGPIOfor PA on/offPALNARF switchRF switchBPFRFoutANT1ANT2DIG3DIG4DIG1 User Manual Version 1.3 2013-06-10 OEM radio modules deRFmega LNA The LNA could be used to amplify the received signal. Please regard the manufacturers datasheet for a proper design. The control could be done by DIG4 signal. Refer to Section 7.2.1 for more information. RF switch for antenna diversity The switch must have 50 inputs and outputs for the RF signal. It is possible to use a separate switch with 2 inputs and 2 outputs or use another (third) switch following the switch required for the PA/LNA. Antenna diversity switching could be controlled via DIG1. Refer to Section 7.2.1 for more information. Certification The customer has to ensure, that custom front-end and antenna diversity designs based on the radio module deRFmega128-22M10 or deRFmega256-23M10 will meet all national regulatory requirements of the assignment location and to have all necessary certifications, device registration or identification numbers. For long range applications we recommend the use of the deRF-mega128-22M12 radio module which already includes PA, LNA, BPF, RF switches and antenna diversity. This module will be provided by dresden elektronik with certified reference designs for EU and US applications that meet all regulatory requirements and reduce custom design costs. www.dresden-elektronik.de Page 58 of 69 User Manual Version 1.3 2013-06-10 11.

Overview ConBee - USB Dongle The ConBee is the platform independent USB Dongle that turns your host into a full functional wireless node which can be seamlessly integrated into ZigBee networks. This will enhance the application range of your host with monitoring and controlling ZigBee networks. ZigBee compatible devices are available from a lot of manufacturers. This USB Dongle contains a powerful radio module with integrated power amplifier and low noise amplifier. Together with the assembled onboard chip antenna which has been optimally tuned ensures a superior RF performance. The ConBee is shipped with a bootloader application for simple firmware uploads and updates. The ZigBee firmware is interfaced by a software called deCONZ which runs on Windows, Linux and Mac OS X and is responsible for ZigBee network control and monitoring. Basically, the USB Dongle is a reference design for the ZigBee radio module deRFmega256-

23M12 by dresden elektronik. 2. Applications Mainly the ConBee is designed to handle ZigBee Light Link (ZLL) and ZigBee Home Automation (ZHA) applications in connection with the ZigBee firmware and software deCONZ. A more detailed description of the ZLL standard, the features, benefits and available certified products can be found on the official alliance website [1]. It is also possible to use a custom firmware for wireless applications. Follow the instructions in Section 5 and Section 10 for detailed instructions on software installation and customer modifications. Note:

Please note that depending on the modifications the radio certification and compliance may become invalid. Please get in contact with us to advise you for a custom FCC certified and/or compliant design. 3. Features The ConBee contains the features listed below.

The functional parts of the ConBee are shown in a schematic overview in Figure 2. The USB Dongle will be supplied by the USB 5.0 V domain. Therefore the USB power supply must be sufficient to support the additional load. An onboard low-drop-out voltage regulator generates a stable 3.3 V voltage to supply the radio module on the USB Dongle. The onboard placed radio module deRFmega256-23M12 by dresden elektronik contains an 8-bit AVR microcontroller with an integrated low-power 2.4 GHz transceiver for ZigBee and IEEE 802.15.4 applications. The ConBee has no pre-installed firmware. You can install the firmware that fits your needs. Each USB Dongle contains a world-wide unique identifier, named MAC-ID. It consists of an 8 byte address, including the vendor ID and product ID. The MAC-ID is stored in the MCU internal EEPROM. www.dresden-elektronik.de Page 7 of 25 User Manual Version 1.0 2016-06-15 ConBee - USB Dongle The RF output signal of the 2.4 GHz radio module is routed to the assembled onboard chip antenna.

Assemble the program header The program header provides the microcontroller programming interface of the radio module. Assemble a 50 mil 10-pin SMT header on the bottom side. We recommend the use of the header FTSH-105-04-LM-DV-P by SAMTEC or a similar item. The header pin description can be found in Section 8 Table 11 . A detailed description of suitable programmers and related software tools are listed in [5]. 1 Program header footprint Figure 3: USB Dongle program header position (default not assembled) Note:

Improper handling in respect of erasing or overwriting the MCU internal flash or EEPROM completely or in parts may result in an unusable USB Dongle unit. Modification of the pre-allocated EEPROM memory sections or removal of the pre-installed bootloader will irreversibly preclude restoring, booting or upgrading the shipping firmware at all. dresden elektronik will not support such modifications (see Section 5.3 for details). 8.2. Assemble the trace header The trace header provides the microcontroller UART interface of the radio module. Assemble a 50 mil 6-pin SMT header on the bottom side. We recommend the use of the header FTSH-

103-01-F-DV by SAMTEC or a similar item. The header pin description can be found in Section 8 Table 11. www.dresden-elektronik.de Page 19 of 25 ConBee - USB Dongle User Manual Version 1.0 2016-06-15 1 Trace header footprint Figure 4: USB Dongle trace header position (default not assembled) 8.3. Assemble the Serial Flash Memory The USB Dongle offers the use of an external Serial Flash Memory for custom application or features. The memory interface is connected to the SPI of the radio module. The provided footprint is SO-8. We recommend the use of a Serial Flash Memory like M25P40-VMN6TPB by MICRON. It is useful to place a stabilizing capacitor of 100nF to the 0402 footprint next to the memory. The signal pin description can be found in Section 8 Table 10. 1 Stabilizing capacitor Serial Flash Memory footprint Figure 5: USB Dongle Serial Flash Memory position (default not assembled) 8.4. Assemble the User button The USB Dongle offers the use of an external user button. We recommend the use of the SMT button KSR211GLFS by ITT or similar items. The button is connected with ground and signal PB7. The signal pin description can be found in Section 8 Table 10Table 11. www.dresden-elektronik.de Page 20 of 25 User Manual Version 1.0 2016-06-15 ConBee - USB Dongle PB7 GND User button footprint Figure 6: USB Dongle user button position (default not assembled) 8.5. Assemble the status LEDs The USB Dongle offers the use of two status LEDs. The first LED is connected with signal PD7 and the second LED is connected with signal PG2. Each LED needs one additional series resistor with a value of 820 Ohms. Both LEDs are low-active. We recommend the use of the following LEDs and resistors:

Red low current LED: TLMS1000-GS08 by Vishay (SMT package 0603) Green low current LED: LG L29K-G2J1-24-Z by OSRAM (SMT package 0603) Resistor 820 Ohms: RC0402FR-07820RL by YAGEO (SMT package 0402) The signal pin description can be found in Section 8 Table 10.
