SX1280 Wireless Module

1. Product Overview

1.1 Brief Introduction

E28-2G4T12S is an UART module based on SEMTECH SX1280, it adopts
transparent transmission and works at 2.4GHz band. It adopts LoRa, FLRC and GFSK
modulations. It features SMD packing with both IPX and PCB antenna interfaces, and
its TTL output is 3.3V.
The LoRa direct sequence
communication range and better anti-interference ability. The forward error correction
(FEC) algorism enables better coding efficiency and error correction ability. The
module will proactively correct the interfered data packets when sudden interference
occurs, which significantly improves the communication range and reliability.
The module features data encryption and compression. The data transmitted in air features randomness, the data encryption
algorism makes data interception meaningless, meanwhile, the data compression function could shorten the transmission duration
and reduce the probability of data interference, thus improves the reliability and transmission efficiency.
