The world's first 1S brushless whoop FC with Betaflight OSD integrated. Suitable for 1S brushless whoop drone like BETAFPV Beta65 Pro, Beta75 Pro or BWhop B06 etc. Nowadays, the upgraded version is available.
1) The output voltage for receiver is switchable between 3.3V and 5V. So pilots could use Spektrum receivers that need 3.3V power. 3.3V in default.
2) The USB port is compatible with the Beta75 Pro frame.
Betaflight OSD (on screen display) is integrated in BETAFPV F3 brushed flight controllers that shows important flight data on your FPV feed, such as battery voltage, current draw and much more. You can even use it as a menu to change your quad’s PID, rates, filters and other settings.
How would do an OSD with the AIO cameras?
There is a video in and out on the fc itself, labeled "I" and "O" as show below. There should be a video in and out on the AIO camera, like BETAFPV H02 etc. If not, you would have to modify the camera for sure but it would totally be worth it. There is some examples.
For old version
BETAFPV H02 Camera, FX806TC, VM275, FX805, Eachine XT02 etc aio camera vtx are available to use the OSD function.
