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. |
