Thanks to Furious FPV for showing me this awesome feature of Betaflight. HOW DID I MISS THIS!!!
If you have an OSD, such as the Furious FPV OSD/vTX board, or the more common MinimOSD, you know that updating certain options requires you to hook up to the board with an FTDI adapter and flash it using Arduino. NO MORE! Betaflight can now do serial passthrough to an OSD, just like it does BLHeli passthrough to the ESCs. This video will show you how.
