1. Overview
1.1 Introduction
E22-400T30S is a wireless serial port module (UART) based
on SEMTECH's SX1268 RF chip. It has multiple transmission
modes, LoRa spread spectrum technology, TTL level output,
compatible with 3.3V and 5V IO port voltage.
With PA and LNA, the power is 1W based on originally
imported SX1262 module, the receiving sensitivity is improved accordingly. LoRa direct sequence spread spectrum
technology will bring longer communication distance, and has the advantages of concentrated power density and
strong anti-interference ability. It is different from FSK and GFSK.
The module has data encryption. Data transmitted over the air, with randomness, makes data interception
meaningless through strict encryption and decryption algorithms. The module reserves multiple IO interfaces to
provide custom development services.It supports packet length setting and also supports different real-time and
data packet.
