Product Descriptions
E22-230T22U, E22-400T22U and E22-900T22U are the new generation of LoRa wireless spread spectrum modules, of which E22-230T22U and E22-900T22U modules are wireless serial modules designed based on SEMTECH's SX1262 chip solution, while
E22-400T22U module is based on SX1268 chip scheme design. With multiple transmission modes, it works in 220.125MHz~236.125MHz (default 230.125MHz), 410.125~493.125MHz (default 433.125MHz), 850.125~930.125MHz band (default 868.125MHz), LoRa spread spectrum technology, 5V of IO port voltage, using USB standard package, convenient for user development and use. Communication compatible with E22-230T/400T/900T series products, support baud rate 1200 ~ 115200 bps.
E22-230T22U, E22-400T22U, E22-900T22U adopt the new generation LoRa spread spectrum technology, compared with the traditional SX1278 solution, this solution has longer transmission distance and faster speed; it supports wireless configuration,
carrier listening, automatic relay, communication key, upgrade firmware and other functions, supports sub-packet length setting, and can provide custom development service.
