[Introduction]：E22-230T30E is a new generation of LoRa wireless 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, works in the 220.125~236.125MHz frequency band, is compatible with 3.3V and 5V IO port voltages, adopts MINI PCI-e standard packaging, and has UART, RS485, RS232, and USB communication interface options to facilitate user development and use. Adopting a new generation of LoRa spread spectrum technology, this solution has longer transmission distance and faster speed; supports air wake-up, wireless configuration, carrier monitoring, automatic relay, communication key and other functions, supports sub-packet length setting, and can provide customized development Serve.
