1
Pin No. Pin Item Pin Direction Pin Application
1 M0 Input(weak pull-up) Work with M1 & decide the four operating modes. Floatingis not allowed, can be ground.
2 M1 Input(weak pull-up) Work with M0 & decide the four operating modes. Floatingis not allowed, can be ground.
3 RXD Input TTL UART inputs, connects to external TXD (MCU, PC) output pin.Can be configured as open-drain or pull-up input.
4 TXD Output TTL UART outputs, connects to external RXD (MCU, PC) input pin.Can be configured as open-drain or push-pull output.
5 AUX Output To indicate module's working status & wakes up the external MCU. During the procedure of self-check initialization, the pin outputs low level. Can be configured as open-drain output or push-pull output (floating is allowed).
6 VCC Input Voltage reference of module. Power supply 3.3V ~ 5.2V DC
7 GND Input Ground
8 RESET Input Reset pin when program is loading(floating,users do not need toconnect)
9 GND Input Ground pin when program isloading (floating,users do not need to connect)
10 SWIM Input SWIM pin when program isloading (floating,users do not need to connect)
11 +3.3V Input Power supply pin whenprogram is loading (floating,users donot need to connect)
12 PB3 Input /Output NC pin,need to be floating,not connected(for further development)
13 PB1 Input /Output NC pin,need to be floating,not connected(for further development)
14 PB0 Input /Output NC pin,need to be floating,not connected(for further development)
15 GND - Ground
