[Introducción]：E32-868T30D UART WIreless Module LoRa módulo Semtech SX1276 chip E32-868T30D es un módulo LoRa de 1W, que opera a 862~893MHz, se basa en el RFIC original importado SX1276 de Semtech, la transmisión transparente está disponible con el nivel TTL. El módulo adopta la tecnología LoRa de espectro amplio, lo que significa que la distancia de transmisión es mucho.
| Pin No | Pin Item | Pin Direction | Pin Application |
|---|---|---|---|
| 1 | M0 | Input（weak pull-up） | Work with M1& decide the four operating modes. (Floating is not allowed, can be ground) |
| 2 | M1 | Input（weak pull-up） | Work with M0 & decide the four operating modes. (Floating is not allowed, can be ground) |
| 3 | RXD | Input | TTL UART inputs, connects to external TXD (MCU, PC) output pin.Can be configured as open-drain or pull-up input. |
| 4 | TXD | Output | TTL UART outputs, connects to external RXD (MCU,PC) input pin.Can be configured as open-drain or push-pull output |
| 5 | AUX | Output | To indicate module's working status & wakes up the external MCU. During the procedure of self-check initialization, the pin outputs low level. Can be configured as open-drain output or push-pull output. (Floating is allowed) |
| 6 | VCC | Input | Power supply 3.3V~5.2V DC |
| 7 | GND | Input | Ground |
