Detail about E32-915T30D Wireless Module

E32-915T30D is a 1W wireless transceiver module with LoRa spread-spectrum technology, operates at 900~931MHz, based on original imported RFIC SX1276 fromSEMTECH, transparent transmission is available, TTL level. The module adopts LoRa spread-spectrum technology, which means the transmitting distance is much longer than before.
