[Introduction]：E32-868T30D Module sans fil UART Module LoRa Puce Semtech SX1276 E32-868T30D est un module LoRa 1 W, il fonctionne à 862 ~ 893 MHz, il est basé sur le RFIC SX1276 importé d'origine de SEMTECH, la transmission transparente est disponible avec le niveau TTL. Le module adopte LoRa technologie à spectre étalé, ce qui signifie que la distance de transmission est grande.
| 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 |
