[Introduction]：The E22-170T30S is a new-generation LoRa wireless data transmission module. Developed based on SEMTECH's high-performance RF chip, this series (UART) LoRa module boasts a maximum transmit power of 33dBm, multiple transmission modes, and an operating frequency range of 150.125MHz to 173.125MHz (factory default: 170.125MHz). It features TTL output and is compatible with 3.3V IO port voltage. This wireless module utilizes the latest generation LoRa spread spectrum technology, resulting in faster speeds, lower power consumption, and a smaller size. It supports functions such as wake-up over air, wireless configuration, carrier sensing, automatic relaying, and communication key authentication. It also supports packet length configuration and offers custom development services.
