Jan 23, 2024

When setting up your quadcopter, having a reliable and effective connection for your receiver and flight controller is essential. If you're planning on wiring your FrSky X4R-SB receiver to a flight controller using the White Noise board or something similar, this step-by-step guide will walk you through the process, ensuring a secure connection and optimal performance for your drone. By following these steps, your wiring and setup will be clean, efficient, and ready for take-off!

Step 1: Gather Necessary Components

To wire your White Noise board to the X4R-SB receiver, you'll need the following components:

  • FrSky X4R-SB receiver
  • White Noise board (or similar)
  • Soldering iron and solder
  • Heat-shrink tubing
  • Wire cutters/strippers
  • Tweezers

Step 2: Prepare the White Noise Board

Start by preparing your White Noise board, following its standard installation procedure, ensuring that all pads are properly tinned and connection points are ready for attachment.

Step 3: Identify Connections on X4R-SB Receiver

On the X4R-SB receiver, you'll find three main connections: SBUS, GND, and 5V. Make sure to identify these points clearly as it's where you'll be soldering the wires from the White Noise board.

Step 4: Prepare Wire Connections

Cut, strip, and tin the necessary wires for your receiver connection. This generally includes three wires: signal, ground, and power.

Step 5: Solder Wires to White Noise Board

Attach the corresponding wires to their respective pads on the White Noise board. Typically, the solder points are labeled as follows:

  • S or SBUS for the signal wire
  • G or GND for the ground wire
  • V or 5V for the power wire

Step 6: Attach Wires to X4R-SB Receiver

Carefully solder the wires prepared in step 3 to the appropriate points on your X4R-SB receiver. Be sure to double-check the connections and ensure they are secure.

Step 7: Insulate and Secure Connections

Once the soldering is complete, slide heat-shrink tubing over the wires and connections, ensuring everything is insulated and secure. Use a heat gun or lighter to shrink the tubing for a snug fit.

Step 8: Test Connection

After your connections are complete, it's a good idea to test the functionality of your setup to ensure everything is working correctly. Connect your flight controller and receiver, and verify that all signals and telemetry are being transmitted properly.

By following these steps, you'll have successfully wired your White Noise board to your FrSky X4R-SB receiver, ensuring a seamless connection and top-notch performance for your drone. With this setup, you'll be ready to fly with confidence and enjoy hassle-free control over your quadcopter!
