E44-TTL-100 LoRa 915MHz SX1276 SX1278 Wireless Module Long Range UART 915 Mhz Transmitter and Receiver

E44-TTL-100 LoRa 915MHz SX1276 SX1278 Wireless Module Long Range UART 915 Mhz Transmitter and Receiver

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.


Features:

  • Model: E44-TTL-100
  • Interface: UART
  • Distance: 3000m
