EByte E28-2G4M27SX 2.4GHz SX1281 RF Transceiver Module

Description

The EByte E28-2G4M27SX is a professional-grade 2.4GHz RF transceiver module built around the Semtech SX1281 radio IC. It is engineered for developers requiring long-range, high-data-rate wireless links in the globally available ISM band. The module’s integrated power amplifier (PA) and low-noise amplifier (LNA) enable a formidable 27 dBm (500mW) transmit output and a sensitive -132 dBm receiver, pushing the practical communication distance to several kilometers in open environments.

Its core strength lies in protocol flexibility, supporting not only standard GFSK but also the efficient FLRC and long-range LoRa modulation schemes at 2.4GHz. This multi-mode capability, combined with Bluetooth 5.1 compatibility, allows a single hardware platform to serve diverse applications from high-speed data telemetry to low-power, sporadic sensor reporting. The module is supplied by a 3.3V SPI interface for configuration and data exchange, making it directly compatible with common microcontrollers like STM32, ESP32, and Raspberry Pi Pico.
