[Introduction]：E310-900T23D is a wireless serial module based on ON Semiconductor's narrow-band Sub-GHz RF transceiver AX5045 solution. Working in the 900.0MHz to 931.0MHz frequency band (default 915.0MHz), it has functions such as half-duplex transparent transmission, air wake-up (ultra-low power consumption) data relay and forwarding (distance extension).
| Pin number | Pin name | Pin Orientation | Pin usage |
|---|---|---|---|
| 1 | M0 | Input (very weakpull-up) | Cooperate with M1 to determine the 4 working modes of the module(can not be suspended, if not used, it can be grounded) |
| 2 | M1 | Input (very weakpull-up) | Cooperate with M0 to determine the 4 working modes of the module(can not be suspended, if not used, it can be grounded) |
| 3 | RXD | Input | TTL serial port input, connected to the external TXD output pin; |
| 4 | TXD | output | TTL serial output, connected to external RXD input pin; |
| 5 | AUX | output | Used to indicate the working status of the module;The user wakes up the external MCU, and outputs a low level during the power-on self-test initialization; (can be left floating) |
| 6 | VCC | Power supply | Module power positive reference, voltage range: 2.3 ~ 5.5V DC |
| 7 | GND | Power supply | Module ground |
| 8 | Fixing hole | - | Fixing hole (connect to GND on the module) |
| 9 | Fixing hole | - | Fixing hole (connect to GND on the module) |
| 10 | Fixing hole | - | Fixing hole (connect to GND on the module) |
