Basic Setup

For advanced configuration see Advanced Settings.

Required Components

• Flight controller with Betaflight, INAV or Ardupilot firmware
• Runcam WiFiLink 1 and the Pixelpilot app
• RTL8812AU Wi-Fi adapter (included with WiFiLink-G)
• USB-C OTG adapter (included with WiFiLink-G)
• Modern Android 13 or 14 smartphone (with powerful CPU for minimal latency)
• Internet connection

Hardware Preparation

1. Attach the antennas to the Runcam.
2. Connect the 4-pin cable to the UART on the flight controller designated for digital VTX (see image), or solder directly to the UART on the FC. Note: wire colors may only match on one end — verify GND to GND, VCC to VCC, etc.
3. Insert a formatted microSD card into the Runcam slot (located on the bottom under the fan).
4. Connect the included Ethernet cable to the device.

Getting the gs.key

1. Insert an empty, formatted microSD card into the Runcam (contacts facing the board). You may need to disassemble the housing.
2. On first boot the device will create user and gs.key files. Remove the card and copy gs.key to your VRX (Android, PC, etc.).

Connecting to Android GS

1. Install the Pixelpilot app.
2. Copy the gs.key file to your smartphone.
3. Connect the RTL8812AU Wi-Fi adapter to your smartphone.
4. Launch Pixelpilot when the pop-up appears.
5. Tap ⚙️ (gear) and set:
   • Channel: 161
   • Bandwidth: 20
6. Select WFB-NG → gs.key and choose the copied file.
7. Power on the VTX.

If video does not appear within 30 seconds:

• Restart Pixelpilot
• Check the lens cap
• Verify the gs.key file
• Restart both the smartphone and the VTX

Summary

After basic setup you will have access to an affordable digital FPV system. OSD is displayed by default on the AIR Unit — to configure OSD on the VRX see OSD Configuration. For the official manufacturer guide see Runcam documentation.
