[Introduction]：E32-433T20DT is a wireless transceiver module based on SX1278 from SEMTECH(can be transmitter and receiver both). It adopts LoRa spread spectrum technology, with this technology the transmitting distance and penetration ability of the module improved more than 1 times compared with traditional FSK.
| 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 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 | Power supply 2.3V-5.2V DC |
| 7 | GND | Input | Ground |
