| Pin No. | Definition | Description |
| 1 | VCC | Connected to the positive power supply (typical 5V) |
| 2 | GND | Connected to ground |
| 3 | TXD/A | connect to A@485 |
| 4 | RXD/B | connect to B@485 |
| 5 | SET | Configuration parameter enable (low level enable parameter configuration, default high level output) |
| 6 | CS | Module enable pin (built-in pull-up) Note: Default factory version: sleep current <200uA, CS pulled high or suspended for normal communication, sleep at low level; Low power consumption version: sleep current <15uA, normal communication when CS is pulled low, pull high or float to sleep. |
