[Introduction]：The EWM22M-900T22S is an ultra-compact and cost-effective wireless serial port (UART) module with multiple transmission modes. It uses LoRa communication technology, fully compatible with the E22. Its maximum transmission power is 22 dBm and operates in the 900 MHz frequency band. It uses LoRa spread spectrum technology, TTL level output, and is compatible with a 3.3 V I/O port voltage. This LoRa module offers higher data rates, lower power consumption, and a smaller footprint. Custom development services are available.
