4 | GND | - | Ground |
5 | M0 | Input (weak pull-up) | Work with M1 to decide 4 working modes of module (not suspended, if not used, could be grounded). |
6 | M1 | Input (weak pull-up) | Work with M0 to decide 4 working modes of module (not suspended, if not used, could be grounded). |
7 | RXD | Input | TTL UART inputs, connects to external (MCU, PC) TXD output pin. |
8 | TXD | Output | TTL UART outputs, connects to external RXD (MCU, PC) input pin. |
9 | AUX | Output | Used to indicate the working status of the module; The user wakes up the external MCU and outputs low level during power-on self-check initialization; (can be left floating) |
