[Introduction]：E22-400T30D is new lora module (UART) based on SEMTECH's SX1268 RF chip. It has multiple transmission modes working at 410.125～ 493.125MHz, LoRa spread spectrum technology, TTL level output, compatible with 3.3V and 5V IO port voltage.
| No. | Name | Direction | Function |
|---|---|---|---|
| 1 | M0 | Input（weak pull-up） | Work with M1 to decide 4 working modes of module (not suspended, if notused, could be grounded). |
| 2 | M1 | Input（weak pull-up） | Work with M0 to decide 4 working modes of module (not suspended, if notused, could be grounded). |
| 3 | RXD | Input | TTL UART inputs, connects to external (MCU, PC) TXD output pin. Can beconfigured as open-drain or pull-up input. Ground |
| 4 | TXD | Output | TTL UART outputs, connects to external RXD (MCU, PC) input pin. Can beconfigured as open-drain or push-pull output |
| 5 | AUX | Output | To indicate module ’s working status & wakes up the external MCU. During theprocedure of self-check initialization, the pin outputs low level. Can beconfigured as push-pull output (can be suspended). |
| 6 | VCC | Input | Power supply ：3.3~ 5.5V DC |
| 7 | GND | Input | Ground |
| 8~11 | Fixed hole | - | Fixed hole |
