2 PWM1 I/O Light driver port/ GPIO pin usage.
3 GND P The reference ground of the module.
4 PWM3 I/O Light driver port/ GPIO pin usage.
6 GPIO3 I/O GPIO port.
8 ADC I/O ADC analog input.
9 GPIO0 I/O GPIO port.
10 nRST I Hardware reset pin, the chip is reset when the pin is LOW; The module comes with a power-on reset, the user can use this pin as needed
11 GPIO2 I/O GPIO port.
TP1 Test point SWCLK JLINK SWCLK programming pin. Can be used as a GPIO pin in normal applications.
TP2 Test point SWDIO JLINK SWCLK programming pin. Can be used as a GPIO pin in normal applications.
TP3 Test point SWO JLINK SWO output pin, can be used as GPIO port in normar applications.

Description: P indicates the power pin, I/O indicates the input/output pin, and AI indicates the analog input pin. RST is only the module hardware reset pin; it cannot clear Zigbee net-pairing information. (1): This pin can only be used as an ADC port. It cannot be used as a normal IO port. If it is not used, it needs to be left floating. As an ADC input, the input voltage range is limited to 0-AVDD and can be configured by software.
