Ebyte Rf Transmitter 433mhz Sx1278 Lora Iot Module wireless rf module 433







[Introduction]:E32-433T20S1 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.
