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