Description
Happymodel OVX300 OpenVTX 500mw 5.8ghz VTx
*Price increase is due to chip shortages, component cost for vtx production has skyrocketed. This is unfortunately unavoidable, and will be effecting all analog vtx brands.
NB: Must be used together with a flight controller that supports Smartaudio, Tramp, or MSP
Power output is listed as 300mw for static power output due to heating, with airflow the vtx outputs consistent >500mw.
– See IRC Power meter readings in image gallery.
Open VTX provides more accurate power output over traditional vtx’s, as well as less “bleed” over adjacent channels.
Happymodel OVX300 and OVX303 VTX’s are based on the Open source project OpenVTX – powered by JyeSmith (EpxressLRS team)
OpenVTx provides firmware for vtxs with better performance, as well as additional features. For use with MSP, SmartAudio, and Tramp protocols. Either protocol can be used on the flight controller, on VTx power up the protocol used is automatically detected by OpenVTx.
Currently SA is fully implemented and test against Rev. 09. To date IMRC has not released a protocol standard and implementation is based on information found within Betaflight.
