[Introduction]:E280-2G4T12S est un module de port série sans fil (UART) basé sur la puce RF SX1280 de SEMTECH, mode de transmission transparent, fonctionnant dans la bande de fréquence 2,4 GHz, avec LoRa, FLRC et GFSK trois technologies de modulation et de démodulation, sortie de niveau TTL, compatible avec 3.3 IO tension de port de V et 5V.
| Pin number | Pin name | Pin direction | Pin usage |
|---|---|---|---|
| 1 | GND | Reference place | Module ground |
| 2 | NC | - | Empty feet not connected |
| 3 | MO | enter | The combination of M2, M1, and M0 determines the 8 working modes of the module (cannot be suspended, if not used, it can be grounded) |
| 4 | M1 | enter | The combination of M2, M1, and M0 determines the 8 working modes of the module (cannot be suspended, if not used, it can be grounded) |
| 5 | M2 | enter | The combination of M2, M1, and M0 determines the 8 working modes of the module (cannot be suspended, if not used, it can be grounded) |
| 6 | RXD | enter | TTL serial port input, connected to the external TXD output pin; can be configured as open-drain or pull-up input, see parameter settings for details |
| 7 | TXD | Output | TTL serial port output, connected to the external RXD input pin; can be configured as open-drain or push-pull output, see parameter settings for details |
| 8 | AUX | Output | Used to indicate the working status of the module, the user wakes up the external MCU, and outputs low level during the power-on self-check initialization period. It can be configured as an open-drain output or push-pull output. For details, see parameter settings (can be left floating) |
