Please create a XT60 version of this PDB.

- Is the USB adapter for flashing firmware included?
- Why no linear regulator on the 5V BEC?
- Do you care about doing a review for this OSD? I'd publish it at http://www.aerosurfer.ch.

USB adapter is not included.

Linear 5V, current is not enough & very hot.

Any plans on a XT60 version? Basically this board with the same OSD?
I'd buy 10 of them straight away!

This board looks promising. Is the 5V/12V output filtered?

12V regulator has linear output so it's meant for camera and vtx. It provides some sort of filtering but the best way is adding a low ESR capacitor where battery leads are soldered on That completely removes any noise.

Yea but what about voltage spikes due to aggressive braking? Also other boards have filtering build in...

I'm still looking for that one PDB/OSD board that makes everything right out of the box.

I just wanna know where to buy. Looks like the rrosd and powerosd pro has some competition. I already like this 1 better I only have high power setups and this thin.g can handle 140a that's very impressive

Ordered one from AliExpress, $16 delivered to UK. Now the wait begins!

That's what low ESR cap is exactly for. To reduce any kind of voltage spiking. Please watch this video and you'll know everything about FPV video noise filtering

After watching that video I'm definitely sold on caps but still, I would wish for a board that has good filtering build in and doesn't require me to add an additional cap.

I used TBS PNP50's in the past and they have excellent filtering build in. Although they have a larger form factor and are more heavier, that's why I switched to RROSD's for now.

I'm aware that there are some technical difficulties to be solved before we see a board that "makes everything right" [TM] but I'm sure it will come out some day and that's what I am waiting for.

Also would like to know where to buy to get out the fastest to the US?
