[Introduction]：E22-230T30D is a new generation of LoRa wireless module. It is a wireless serial port module (UART) based on SEMTECH's LoRa solution radio frequency chip. It has a variety of transmission methods and works in the (220.125~236.125MHz) frequency band (default 230.125MHz). LoRa spread spectrum technology, TTL level output, compatible with 3.3V and 5V IO port voltages.
