Ebyte E280-2G4T12S SX1280 2.4GHz 12dBm 3km Long Range UART LoRa Wireless Module

Ebyte E280-2G4T12S SX1280 2.4GHz 12dBm 3km Long Range UART LoRa Wireless Module

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.
