E280-2G4T12S Wireless ranging SX1280 12dBm 2.4G 3km Long Range TTL Rf Receiver Wireless UART Lora Module

Product Descriptions

E280-2G4T12S is a wireless serial port module (UART) based on SEMTECH's SX1280 RF chip, transparent transmission mode, working in 2.4GHz frequency band, with LoRa, FLRC and GFSK three modulation and demodulation technologies, TTL level 

output, compatible with 3.3 IO port voltage of V and 5V. 

E280-2G4T12S adds a wireless ranging function on the basis of the traditional serial port module. Based on an improved binary backoff algorithm, it uses adaptive frequency hopping technology to integrate Kalman filtering, which can effectively resist 

wireless interference and improve the ranging accuracy. 

LoRa direct sequence spread spectrum technology will bring longer communication distance, and has the advantages of wider power spectrum and strong anti-interference ability. The module has a hardware FEC forward error correction algorithm, 

which has high coding efficiency and strong error correction ability. In the case of sudden interference, it can actively correct the interfered data packet, which greatly improves the reliability and transmission distance. 

The module has data encryption and compression functions. The data transmitted by the module in the air is random, and the data interception is meaningless through strict encryption and decryption algorithms. The data compression function has the 

possibility to reduce the transmission time, reduce the probability of interference, and improve the reliability and transmission efficiency.
