[IC] : SX1278

[Frequency] : 410~441MHz

[Power] : 10~20dBm

[Distance] : 3.0km

[Interface] : UART

[introduction] : E32-433T20DT is a wireless transceiver module based on SX1278 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.
