[Introduction]：E22-230T22U is a new generation of LoRa spread spectrum module, a wireless serial port module designed based on SEMTECH's LoRa solution radio frequency chip. It has a variety of transmission methods, working at 220.125MHz~236.125MHz (default 230.125MHz), LoRa spread spectrum technology, 5V IO port voltage, and USB standard packaging, which is convenient for users to develop and use. The communication is compatible with E22-230T/400T/900T series products and supports baud rate of 1200~115200bps. Supports wireless configuration, carrier monitoring, automatic relay, communication keys, firmware upgrade and other functions, supports sub-packet length setting, and can provide customized development services.
