Pin No. | Pin Item | Pin Direction | Pin Application |
---|---|---|---|
1 | M0 | Input(weak pull-up) | Work with M1 & decide the four operating modes. (Floating is not allowed, can be ground) |
2 | M1 | Input(weak pull-up) | Work with M0 & decide the four operating modes. (Floating is not allowed, can be ground) |
3 | RXD | Input | TTL UART inputs, connects to external (MCU, PC) TXD 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 | Power supply 2.3V~5.5V DC |
7 | GND | Input | Ground electrode |
8 | ANT | Output | Antenna interface( high frequency signal output) |
9 | GND | Output | Reference places of high frequency signal output |
10 | GND | Input | Ground electrode |
11 | GND | Input | Ground electrode |
