OpenVTx
Open source firmware for FPV video transmitters supporting MSP, SmartAudio, and Tramp protocols with automatic detection.
What is OpenVTx?
OpenVTx is an open-source firmware for FPV drone video transmitters that supports MSP, SmartAudio, and Tramp communication protocols. It allows pilots to control VTx settings like frequency and power directly from their flight controller, with automatic protocol detection and VTx table configuration. The project aims to provide a vendor-neutral, feature-rich alternative to proprietary VTx firmware.
FPV drone enthusiasts, racers, and DIY builders who use video transmitters compatible with MSP, SmartAudio, or Tramp protocols and want enhanced control and configurability.
Developers choose OpenVTx for its protocol flexibility, automatic detection, and deep integration with Betaflight, offering a unified, open-source solution that reduces vendor lock-in and improves the FPV experience.
