Product Descriptions
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 spread spectrum (DSSS) enables longer 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.
