[Introduction]：The E28-2G4T20SX is a UART wireless serial port module from Ebitech based on the SEMTECH SX1281 RF chip. It supports transparent transmission, operates in the 2.4GHz band, and features LoRa, FLRC, and GFSK modulation/demodulation technologies, with TTL level output. This LoRa wireless module includes data encryption and compression functions. Since data transmitted over the air is random, robust encryption and decryption algorithms enhance data transmission security. Data compression reduces transmission time and the probability of interference, improving reliability and transmission efficiency.
