[Introduction]:E32-868T30S is a wireless transceiver module based on SX1276 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.

1
Pin No. Pin Item Pin Direction Pin Application
1 M0 Input(weak pull-up)    Work with M1 & decide the four operating modes. Floatingis not allowed, can be ground.
2 M1 Input(weak pull-up)    Work with M0 & decide the four operating modes. Floatingis 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    Voltage reference of module. Power supply 3.3V ~ 5.2V DC
7 GND Input    Ground
8 RESET Input    Reset pin when program is loading(floating,users do not need toconnect)
9 GND Input    Ground pin when program isloading (floating,users do not need to connect)
10 SWIM Input    SWIM pin when program isloading (floating,users do not need to connect)
11 +3.3V Input    Power supply pin whenprogram is loading (floating,users donot need to connect)
