1.Overview
1.1 Introduction
E22-230T22S is a wireless serial port module
(UART) based on SEMTECH's SX1262 RF chip. It has
multiple transmission modes, working in the
220.125MHz~236.125MHz,
(default 230.125MHz),
LoRa spread spectrum technology, TTL level output,
compatible with 3.3V and 5V IO port voltage.

technology will bring longer communication distance, and has the advantages of concentrated power
density and strong anti-interference ability. The module has a software FEC forward error correction
algorithm, which has high coding efficiency and strong error correction capability. In the case of
sudden interference, it can actively correct the interfered data packets, greatly improving reliability and
transmission distance. When without FEC, such packets can only be discarded.
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 packets.
1.2 Features
Communication distance tested is up to 7km;
Maximum transmission power of 160mW, software multi-level adjustable；
Support the global license-free ISM 230.125MHz band；
