Product introduction: E22-900T33S is a new generation of LoRa wireless module, based on SX1262 RF chip wireless serial module (UART), with a variety of 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. The LoRa module adopts a new generation of LoRa spread spectrum technology, which has a longer transmission distance, faster speed, lower power consumption and smaller size than the traditional SX1276 solution. Support air wake-up, wireless configuration, carrier monitoring, automatic relay, communication key and other functions, support subpacket length setting, can provide customized development services.
