Note:

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. Please avoid to place any electrical components,

wiring or grounding under PCB antenna area on main board and it’s better to leave this area

blank on PCB.
