2.4GHz PA+LNA Enhanced RF Module

Each module measures approximately 3.5 × 1.8 × 0.8 cm and weighs ~8 g. It features a 2.4–2.5 GHz operating frequency, 125 selectable channels, PA gain of 20 dB and LNA gain of 10 dB. The module operates at 3.0–3.6 V (recommended 3.3 V), draws up to 115 mA during transmission and 45 mA during reception. Constructed with plastic housing and metal SMA connector, it includes an onboard 3.3 V regulator accepting 5 V input and 5 V-tolerant SPI pins for direct microcontroller interfacing. The SMD LED indicator provides visual status feedback. Designed for bidirectional communication with auto-acknowledge and auto-retransmit functionality across up to six data pipes. Ideal for wireless remote control, smart home sensors, somatosensory devices, RFID/NFC extensions, smart grid monitoring and low-latency wireless audio links where extended range and stable 2.4 GHz performance are required.
