[Introduction]：E150-400T22S is a wireless serial port module (UART) based on LoRa radio frequency chip, which works in the frequency band of 410.125～493.125MHz (default 433.125MHz) and adopts LoRa spread spectrum technology. The wireless acquisition module integrates (switch input) DI, (switch output) DO, (digital-to-analog converter) ADC, (analog-to-digital converter) DAC, (pulse width modulation) PWM and (remote radio) LoRa functions. Users can send Modbus RTU commands through the serial port or remote LoRa networking equipment for control, and it also supports low power consumption mode. The wireless acquisition control module supports LoRa direct sequence spread spectrum technology function, has the advantages of longer communication distance, strong anti-interference ability, and strong confidentiality; industrial-grade passive crystal oscillator ensures its stability and consistency.
