    E32-915T30S (former E44-TTL-1W) is a 1W wireless transceiver module with LoRa spread-spectrum technology, it operates at 900~931MHz (Default: 915MHz), It is based on original imported RFIC SX1276 of SEMTECH with transparent transmission is available and 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.
