The EByte E28-2G4T27SX is a professional-grade 2.4GHz ISM band RF module engineered for demanding wireless data links. Its core is the Semtech SX1281 transceiver, which provides a versatile mix of long-range LoRa spread-spectrum modulation and high-speed FLRC/GFSK modes, configurable for data rates up to 2 Mbps. This allows system designers to optimize for either maximum range or throughput.
Built for industrial IoT and telemetry, the module’s +27 dBm output power and exceptional -134 dBm receiver sensitivity ensure reliable communication over distances up to 7 kilometers in open space. Power management is efficient, with a typical receive current of 27mA, supporting battery-operated sensor networks. The transparent UART interface abstracts all RF complexity, presenting a simple serial pipe for data, drastically reducing development time and firmware overhead.
