PRBMD02 DATASHEET 1.10 K-SOLUTION 14 GPIO and interfaces Every GPIO can be congured as Input, Output and Interrupt, and can also be congured as weak pull-up, strong pull-up, weak pull-low or oating mode. Except ADC, all interfaces are possible to map to different GPIOs by software. The interface including:

1. 2. 3. UART: Asynchronous Rx/Tx, up to almost 1Mbps, supports parity and 9 bit-data 4. PWM: 6 channels PWM is multiplex with GPIO, and the frequency is base on the main I2C: it supports 100KHz and 400KHz modes, 7-bit and 10-bit address I2S: either master or slave mode can be enabled clock (16MHz) as the following equation:

Freq_PWM=16MHz/(N_prescaler x N_top_count);

where the value in N_top_count register controls the frequency and the Duty cycle is controlled by the following equation:

Duty_cycle_PWM=N_threshold/N_top_count where the value in N_threshold, together with N_top_count, control the duty cycle 5.

The rmware basic feature is to tunnel data between UART port and Bluetooth device (Transparent mode). User can develop their own rmware by SDK as well if default rmware is not applicable. AT-CMD and Transparent Modes The rmware contains two modes: AT-CMD mode and Transparent mode. In AT-CMD mode, PRBMD02 accepts AT-command from UART port and change the conguration;

in Transparent mode, ALL data from UART port will forward to Bluetooth and vice versa. PRBMD02 with default rmware UART port MCU data from BLE appears on UART_TX pin automatically data sent to UART_RX pin will automatically forward to BLE side TRANSPARENT mode description PRBMD02 with default rmware UART port set Baud rate set advertising name set module GPIOs AT-CMD mode description MCU PRBMD02 DATASHEET 1.10 K-SOLUTION 20 Mode switching The switching between AT-CMD and Transparent mode is automatically. When PRBMD02 is NOT connected with smartphone, tablet, PRBMD02 will enter AT-CMD mode and AT-command will be accepted from UART port; and once PRBMD02 is connected to with smartphone or any other BT device, PRBMD02 will automatically go into Transparent mode, and all data from UART, even AT-CMD, will be treated as data and send out to BT side. The operation is illustrated as following:

Pin assignment in PRBMD02 P34: BT_Connect, it is used to connect with LED to indicate the BT connection status. Before connection, this pin will toggle at about 2Hz frequency, and after a connection is established, this pin will turn to LOW status P09: UART_Tx, Firmware dene it as Tx pin of UART, which is supposed to be connect to UART Rx pin of MCU or other device. P10: UART_Rx, Firmware dene it as Rx pin of UART, which is supposed to be connect to UART Tx pin of MCU or other device.

PRBMD02 DATASHEET 1.10 K-SOLUTION 23 Mounting guide PRBMD02 is RF sensitive; in order to obtain the best performance, it is recommended to mount the module at corner of mother board, and with some marginal space. Also, keep it away from metal components, such like speakers, transformers, batteries, big aluminum capacitors, heat sinks and Metal Panels. The gure below illustrates how to mount the PRBMD02 module. Improper mounting will decrease the RF performance dramatically.

-Consult the dealer or an experienced radio/TV technician for help NOTE: The manufacturer is not responsible for any radio or TV interference caused by unauthorized modications to this equipment. Such modications could void the users authority to operate the equipment. RF Exposure This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. PRBMD02 DATASHEET 1.10 K-SOLUTION 33 To be updated ORIGINAL EQUIPMENT MANUFACTURER (OEM) NOTES The OEM must certify the final end product to comply with unintentional radiators (FCC Sections 15.107 and 15.109) before declaring compliance of the final product to Part 15 of the FCC rules and regulations. Integration into devices that are directly or indirectly connected to AC lines must add with Class II Permissive Change. The OEM must comply with the FCC labeling requirements. If the modules label is not visible when installed, then an additional permanent label must be applied on the outside of the finished product which states:

Contains transmitter module FCC ID: xxxxxxxxxxx. Additionally, the following statement should be included on the label and in the final products user manual: This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

(1) This device may not cause harmful interferences, and

(2) this device must accept any interference received, including interference that may cause undesired operation. The module is limited to installation in mobile or fixed applications. Separate approval is required for all other operating configurations, including portable configuration with respect to Part 2.1093 and different antenna configurations. A module or modules can only be used without additional authorizations if they have been tested and granted under the same intended enduse operational conditions, including simultaneous transmission operations. When they have not been tested and granted in this manner, additional testing and/or FCC application filing may be required. The most straightforward approach to address additional testing conditions is to have the grantee responsible for the certification of at least one of the modules submit a permissive change application. When having a module grantee file a permissive change is not practical or feasible, the following guidance provides some additional options for host manufacturers. Integrations using modules where additional testing and/or FCC application filing(s) may be required are: (A) a module used in devices requiring additional RF exposure compliance information (e.g., MPE evaluation or SAR testing); (B) limited and/or split modules not meeting all of the module requirements; and (C) simultaneous transmissions for independent collocated transmitters not previously granted together. This Module is full modular approval, it is limited to OEM installation ONLY. Integration into devices that are directly or indirectly connected to AC lines must add with Class II Permissive Change. (OEM) Integrator has to assure compliance of the entire end product include the integrated Module. Additional measurements (15B) and/or equipment authorizations (e.g. Verification) may need to be addressed depending on co-location or simultaneous transmission issues if applicable. (OEM) Integrator is reminded to assure that these installation instructions will not be made available to the end user PRBMD02 DATASHEET 1.10 K-SOLUTION 34 To be updated Operating FrequencyBluetooth LE2402-2480MHz RF output power(Max)-3.08dBm Manufacturer information:
