Features:

Model: E32-TTL-100
E32-TTL-100 is a wireless transceiver module based on SX1278 from SEMTECH(can be transmitter and receiver both).
It 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.
E32-TTL-100 can be compatible with other E32 modules.
