Product Descriptions
E28-2G4T27SX is an UART module based on SEMTECH SX1281, 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, compatible
with 3.3V and 5V IO port voltage. 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. Antenna is optional (IPEX / stamp hole), which is convenient for
user's secondary development and integration.
