    E32-433T20S2T is a wireless transceiver module based on SX1278 of SEMTECH (it can be transmitter and receiver both). It adopts LoRa spread spectrum technology, with this technology the transmitting distance and diffraction of the module improved greatly compared with traditional FSK.The module features FEC (forward error correction) algorithm, which ensure it’s good anti-interference ability. E32 (433T20S2T) can be compatible with other Ebyte E32 modules.
