E32-915T20D is a 100mW wireless transceiver module with LoRa spread-spectrum technology, operates at 900~931MHz (Default: 915MHz), based on originally imported RFIC SX1276 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 advantages of this module is more concentrated power density and better anti-interference performance. |
