EBYTE E28-2G4M20S

E28-2G4M20S is a 2.4GHz RF transceiver module with 100mW transmit power, long communication range, and ultra-low current consumption in low-power mode. The module features a compact SMD form factor with 1.27mm pin pitch, an integrated high-performance PCB on-board antenna, and a 52MHz high-precision low-temperature-drift active crystal oscillator for stable performance. Based on the SX1281 RF chip, the module supports multiple physical layers and modulation schemes including LoRa, FLRC, and GFSK, with Bluetooth protocol compatibility. The integrated power amplifier and LNA deliver up to 100mW maximum transmit power while simultaneously enhancing receive sensitivity, greatly improving communication reliability. Excellent low-power performance, on-chip DC-DC conversion, and time-of-flight measurement capability make this a highly versatile module suitable for smart home, security systems, positioning and tracking, wearable devices, and more. RSSI is supported for custom secondary development. Note: this is a pure RF transceiver module and requires an MCU or dedicated SPI debug tool for operation.
