[Transmission power]：37dBm
[Communication distance]：25km
[Introduction]：E22-230T37S is a new generation of LoRa wireless module. It is a wireless serial module (UART) based on SX1262 radio frequency chip. It has multiple transmission methods, works in the 230MHz frequency band, TTL level output, and supports 4.5V-15V power supply voltage. The LoRa module adopts a new generation of LoRa spread spectrum technology. Compared with the traditional SX1278 solution, the SX126X is farther, faster, lower power consumption, and smaller; it supports air wake-up, wireless configuration, carrier monitoring, automatic relay, and communication encryption. Key and other functions, support subpackage length setting, and provide customized development services.
