Detail about E32-915T20D Wireless Module

E32-915T20D is a 100mW wireless transceiver module, operates at 900~931MHz, based on original imported RFIC SX1276 fromSEMTECH. The module adopts LoRa spread-spectrum technology, which means the transmitting distance is much longer than before.

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).
