Key Features

  • Extended Range up to 1000m – Thanks to integrated PA (Power Amplifier) and LNA (Low-Noise Amplifier) 

  • High Output Power up to 20dBm – Strong signal that effectively penetrates obstacles 

  • Superior Receiver Sensitivity down to -104dBm – Captures weak signals clearly 

  • Three Selectable Data Rates – 250kbps, 1Mbps, 2Mbps (slower rate = longer range) 

  • 125 Adjustable Frequency Channels – Flexibility to avoid interference with other devices 

  • Multi-Node Communication – A single module can communicate with up to 6 other devices 

  • External SMA Antenna – Features an external antenna for improved performance, replaceable with higher-gain options

⚠️ Critical Important Notes

  • ⚠️ Voltage: The module operates on 3.3V ONLY. Connecting to 5V will permanently damage it .

  • ⚠️ Power Supply: The module draws up to 115mA during transmission. The Arduino 3.3V pin cannot supply this current. Use an external 3.3V regulator (e.g., AMS1117-3.3) .

  • ⚠️ 10µF Capacitor: It is highly recommended to add a 10µF capacitor between VCC and GND near the module to stabilize the power supply .

  • ⚠️ Line of Sight: Maximum range requires a clear line of sight. Avoid metal obstacles and sources of interference .
