  • E32-TTL-100 is a wireless transceiver module based on SX1278 from SEMTECH(can be transmitter and receiver both).
  • Adopts LoRa spread spectrum technology, with this technology the transmitting distance and penetration ability of the module improved more than 1 times compared with traditional FSK.
  • The module features FEC (forward error correction) algorithm, which ensure it’s good anti-interference ability.
  • Fine workmanship and stable performance.
  • AS32-TTL-100 can be compatible with other E32 modules.
