[Introduction]：E22-400T33E is a new generation LoRa wireless spread spectrum module based on SEMTECH's LoRa solution. It has a variety of transmission methods, works in the 410.125-493.125MHz frequency band (default 433.125MHz), LoRa spread spectrum technology, compatible with 3.3V and 5V IO port voltage, adopts MINI PCI-e standard packaging, and has UART/RS485/RS232/USB communication The interface is optional and the communication is compatible with E22-T series products, which is convenient for users to develop and use. The module has longer transmission distance and faster speed; supports over-the-air wake-up, wireless configuration, carrier listening, automatic relay, communication key and other functions, supports packet length setting, and can provide customized development services.
