[Introduction]：EWM220M-400T22S is a new generation of LoRa wireless serial port module (UART). It has multiple transmission modes, works in the 410.125~493.125MHz frequency band (default 433.125MHz), LoRa spread spectrum technology, TTL level output, and is compatible with 3.3V and 5V IO port voltages. The LoRa module has long transmission distance, fast speed, low power consumption, small size, and high cost performance; it supports air wake-up, carrier monitoring, communication key and other functions, supports sub-packet length setting, and can provide customized development services. This product can cover an ultra-wide frequency range of 410~493MHz.
