Overview
EBYTE E32-433T30D is a 1W wireless transceiver module with LoRa spread-spectrum technology, operate at 410~441MHz(default: 433MHz), based on original imported RFIC SX1278 from SEMTECH, transparent transmission is available, TTL level. The module adopts LoRa spread-spectrum technology, which means the transmitting distance is much longer than before. The advantage of this module is more concentrated power density and better anti-interference performance.
