Pin Definitions
| Serial number | Pin | Pin direction | Remarks |
|---|---|---|---|
| 1 | MO | Input (very weak pull-up) | Cooperate with Ml to determine the working mode of the module (cannot be suspended, if not used, it can be grounded) |
| 2 | MI | Input (very weak pull-up) | Cooperate with MO to determine the working mode of the module (cannot be suspended, ground if not used) |
| 3 | RXD | Input | TTL serial port input, connected to the external TXD pin (can be configured as an open-drain or pull-up input) |
| 4 | TXD | Output | TTL serial output, connected to the external RXD pin (can be configured as open-drain or push-pull output) |
| 5 | AUX | Output (can be suspended) | Indicates the working status of the module, the user wakes up the MCU externally, and outputs low level during automatic initialization at power-on |
| 6 | VCC | Input | Module power supply test, voltage range: 3.3V ~5.2VDC |
| 7 | GND | Input | Module ground |
| 8 | Fixed hole | Fixing hole | |
