[Introduction] : E22-230T22S is a wireless UART module based on SEMTECH SX1262. It has multiple transmission modes working in the 220.125MHz~236.125MHz. Adopting the new LoRa spread spectrum, It has longer transmisstion distance, lower power consumption, smaller size than SX1278,supporting WOR, wirless configuration, carrier sense, relay networking function.
