Chapter 1 Product Overview

1.1 Product introduction

E150-400T30S is a wireless serial port module (UART) based on
LoRa radio frequency chip. It works in the frequency band of
410.125~493.125MHz (default 433.125MHz) and adopts LoRa spread
spectrum technology.
The 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 and other functions, users can Send Modbus RTU command
to control through serial port or remote LoRa networking device, and also support low power consumption mode.
The module supports the function of LoRa direct sequence spread spectrum technology, which has the advantages
of longer communication distance, strong anti-interference ability, and strong confidentiality. The module's
factory default air rate is 2.4kbps, and the transmit power is 30dBm. The PA power amplifier and LNA low noise
amplifier are integrated inside, thereby improving communication stability and extending communication distance;
industrial-grade passive crystal oscillator is used to ensure its stability and consistency .
