TinysLEDs RealPit VTX Power Switch

The TinysLEDs RealPit VTX Power Switch is a micro-sized inline relay that allows you to completely shut off power to your video transmitter via an auxiliary switch on your radio. Ideal for both analogue and digital FPV builds, this module prevents your VTX from overheating during bench configuration or long waits on the starting grid. It also ensures you never accidentally blast over other pilots' video feeds when plugging in your battery.

Key features

• Remotely toggles power to your VTX, camera, or LED circuits directly from your radio transmitter.
• Prevents thermal throttling on the bench and eliminates channel bleed on the flight line.
• Supports both analogue and standalone digital FPV video transmitters.
• Triggered natively by Betaflight and INAV using the PINIO resource mapping.
• Installs inline between the flight controller and VTX, taking up minimal frame space.

To set up the RealPit, you will need an available logic pad on your flight controller (such as LED_STRIP or an unused UART) and basic familiarity with the Betaflight CLI to map the USER1 mode to the corresponding PINIO resource. Ensure your VTX's maximum continuous current draw falls within standard ranges before wiring it directly through the switch.
