[Introduction]：E22-400T30E is a new generation of LoRa wireless module. It is designed based on the wireless serial port module (UART) of SEMTECH's RF chip and the original SX1268 chip scheme of SEMTECH. It has a variety of transmission methods, works in the (410.125 ~ 493.125MHz) frequency band (default 433.125MHz), LoRa spread spectrum technology, TTL level output, compatible with 3.3V and 5V IO port voltage.
