[Introduction]：E220P-400T22S adopts the new generation of LoRa spread spectrum technology, a wireless serial port module (UART) designed based on LLCC68 RF chip solution, and a built-in LNA, active temperature compensated crystal oscillator and receiving limiter in the wireless module. Under ideal conditions, the communication distance can reach 7km (5.6km for E220-400T22S), with stronger anti-interference ability and longer receiving distance. It supports functions such as air wake-up, carrier monitoring, communication key, and sub-packet length setting, and can provide customized development services.
