E22-900T33S is a new generation of LoRa wireless module, based on SX1262 radio frequency chip wireless serial port module (UART), with multiple transmission methods, working in the 850.125~930.125MHz frequency band, LoRa spread spectrum technology, TTL level output, compatible with 3.3V and 5V IO port voltage. Compared with the traditional SX1276 solution, the transmission distance is longer, the speed is faster, the power consumption is lower, and the size is smaller. It supports over-the-air wake-up, wireless configuration, carrier monitoring, automatic relay, communication key and other functions, supports sub-packet length setting, and can provide customized development services.
