Product Images shown are for illustrative purposes only and may differ from the actual Product. Due to differences in PCB manufacturers, colours, pin mappings, markings & packaging of products/PCBs may also differ from those shown above.

E44-TTL-100 is a 100mW wireless transceiver module with LoRa spread-spectrum technology,operates at 900~931MHz (Default: 915MHz), 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 beforeules.
