[Introduction]：E22-400T33S is a wireless serial port module (UART) based on SEMTECH's SX1268, working at 410.125 ～ 493.125MHz (default 433.125MHz),TTL level output, compatible with 3.3V and 5V IO port voltage. Compared with the traditional SX1278 solution, it has a longer transmission distance, faster speed, lower power consumption, and smaller size; it supports functions such as air wake-up, wireless configuration, carrier monitoring, automatic relay. communication keys and sub-package length setting. Ebyte provides customized development services on it. An obvious advantage is that SX1268 covers wider frequency range.
