[Introduction]：E32-900T30D est un module de port série sans fil (UART) basé sur la puce RF SX1276 de SEMTECH. Il dispose de plusieurs modes de transmission, fonctionnant dans la technologie de spectre étalé LoRa 862 MHz ~ 931 MHz, sortie TTL.
| No. | Item | Direction | Remark |
|---|---|---|---|
| 1 | M0 | Input（weak pull-up） | With M1, the four working modes of the module can be determined (it cannot be suspended, and it can be grounded if it is not used). |
| 2 | M1 | Input（weak pull-up） | With M0, the four working modes of the module can be determined (it cannot be suspended, and it can be grounded if it is not used). |
| 3 | RXD | Input | TTL UART input ,Connect to external TXD output pins; Can be configured as drain open circuit or pull up input, see parameter Settings |
| 4 | TXD | Output | TTL UART output, Connect to external RXD input pin; Can be configured as drain open circuit or push - pull output, see parameter Settings |
| 5 | AUX | Output | Used to indicate the working status of the module; The user wakes up the external MCU and outputs low level during self-test initialization; Can be configured as drain open output, or push-pull output, see parameter Settings(can be suspended) |
| 6 | VCC | Input | Positive reference of module power supply, voltage range: 3.3v ~ 5.5V DC |
| 7 | GND | Input | Ground |
