Pin Specification

Pin No. Name Pin Direction Pin Application
1 MD0 Input (very weak pull up) Cooperates with MD1 to decide 4 kinds of work modes, which cannot be floated
2 MD1 Input (very weak pull up) Cooperates with MD0 to decide 4 kinds of work modes, cannot be floated
3 RDX Input TTL UART inputs, connected to the external TXD output pin. It can be configured as open-drain or pull-up input, see parameter setting
4 TXD Output TTL UART outputs, connected to the external RXD input pin. It can be configured as open-drain or pull-up output, see parameter setting
5 AUX Output Used to indicate the working status of the module, the user wakes up the external MCU; during the initial power-on self-test period, it outputs low. It can be configured as an open-drain output, or push-pull output, see parameter settings
6 VCC Power Input Power input, power supply 2.5-5.5V (Note: if it is less than 4.5V, the output power will decline, but the impact on the reception performance is very small.)
7 GND Ground Ground line, connected to the power supply reference ground.
