Introduction
The E28-2G4T12S is a UART module based on the SX1281, featuring transparent transmission and operating in the 2.4GHz band with support for LoRa, FLRC, and GFSK modulation. It adopts an SMD package and provides both IPX and PCB antenna interfaces, with a 3.3V TTL output. LoRa direct sequence spread spectrum technology enables longer communication range and superior anti-interference capability. The forward error correction algorithm delivers excellent coding efficiency and error correction performance. When burst interference occurs, the module can actively correct corrupted packets, significantly improving communication range and reliability. The module features built-in data encryption and compression. Data transmitted over the air is randomized, rendering interception meaningless through the encryption algorithm. Meanwhile, the data compression function shortens transmission duration and reduces the probability of data interference, thereby enhancing reliability and transmission efficiency.
