The Happymodel OVX300 VTX is based on the Open source project OpenVTX powered by JyeSmith from the EpxressLRS team. Open VTX aims to provide firmware with both the SmartAudio and Tramp protocols. Either protocol can be used on the flight controller and on VTx power up the protocol used is automatically detected by OpenVTx.
