1. In default, UART2 (pin1 and pin2) are used for bypass communication and UART0
(pin16 and pin17) are used for output of debugging information and burning firmware. Please refer to the description in DC Characteristics for UART output current level. 2. PDN is hardware reset for the module and will be effective with VIL. Configuration information will be remained after module reset. The module has pull-up process for PDN designed internally. 3. In default, PIN13 (GPIO8) is the PIN for external LED indicator to show the module configuration status and output VIH after configuration is successful. 4. In default, PIN14 (GPIO5) is the module software reset PIN and will be effective with VIH. The previous configuration information will be cleared after the module is reset (reset to factory settings). 5. The module supports max 4 channels of external interruption simultaneously except GPIO25 and UART0. 6. The ADC is 10bit with input voltage 0-2V 7. The power supply VDD should not be lower than 3.3V. 4.3. PCB Antenna Please refer to Fig 2 for PCB antenna.

For devices with 3.3V power supply, you can directly connect the device UART port with module UART port according to the illustration in Fig Fig 7. External MCU Wi-Fi module Capacitor Grounding Fig 7 Circuit diagram (3.3V) If your device is powered by 5V, you can refer to the circuit shown in Fig Fig 8 or design your own circuit for power conversion. The value of resistor can be adjusted according to actual circuit design.

Fig 8 Circuit diagram (5V) 5.2. Power Supply Requirement If an LDO is used to supply the module with 3.3V power, C1 capacitor can be considered to be used with 10u-22u; If a DCDC is used to supply 3.3V power, C1 capacitor can be considered to be used with 22uF. It is recommended to supply the module with power higher than 400mA to ensure enough power supply to the module and avoid power down during data transmission.

(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that may cause undesired operation. Note: This product has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This product generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this product does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. Please take attention that changes or modification not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. This equipment complies with FCC/IC RSS-102 radiation exposure limits set forth for an uncontrolled environment.

2.9 Information on test modes and additional testing requirements Contact Hangzhou BroadLink Technology Co., Ltd. will provide stand-alone modular transmitter test mode. Additional testing and certification may be necessary when multiple modules are used in a host. 2.10 Additional testing, Part 15 Subpart B disclaimer To ensure compliance with all non-transmitter functions the host manufacturer is responsible for ensuring compliance with the module(s) installed and fully operational. For example, if a host was previously authorized as an unintentional radiator under the Suppliers Declaration of Conformity procedure without a transmitter certified module and a module is added, the host manufacturer is responsible for ensuring that the after the module is installed and operational the host continues to be compliant with the Part 15B unintentional radiator requirements. Since this may depend on the details of how the module is integrated with the host, Hangzhou BroadLink Technology Co., Ltd.shall provide guidance to the host manufacturer for compliance with the Part 15B requirements.
