[Introduction]：E32-433T20S2T, based on SX1278 of SEMTECH, is a 100mW wireless transceiver module operating at 410 ~ 441MHz (default 433MHz) with LoRa spread-spectrum technology. It features FEC (Forward Error Correction) algorithm and data encryption & compression function.
| Pin No. | Pin Item | Pin Direction | Pin Application |
|---|---|---|---|
| 1 | M0 | Input（weakpull-up） | Work with M1 & decide the four operating modes. Floating is not allowed, can be ground. |
| 2 | M1 | Input（weakpull-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.To wake 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 | Voltage reference of module, power supply 2.3V ~ 5.2V DC |
| 7 | GND | Input | Ground |
| 8 | ANT | Output | Antenna interface (high frequency signal output). |
| 9 | GND | Output | Reference places of high frequency signal output. |
| 10 | GND | Input | Ground |
| 11 | GND | Input | Ground |
