Josh Bardwell and RDQ have come togehter to create this next level flight controller. With the latest features, a layout which will make your build clean and easy at an extremely good price.
When setup appropriately, the Bardwell F4 *should* not need any capacitors in order to have clean video. However, on certain setups it will simply be unavoidable. Here are tips on how to setup your board for best video quality and the least likelihood of needing capacitors for perfect video.
The general idea is that you want to limit your camera and VTX's exposure to noise. I.E. - you want to limit exposure to your Bardwell F4, since the noise is produced by your ESCs, then passed through the Flight Controller to your VTX AND your Camera. A common misconception is that noise shows itself only through the VTX, when in fact it can be shown to your video via your Camera. So, here are our tips:
Can your VTX power your Camera? If yes, power your Camera straight off your VTX 100% of the time. If no, then use the supplied camera power pads on the Flight Controller. If you aren't using it, don't wire it! Not using OSD or camera control? Then wire your camera's video straight to your VTX (not through the video pads on the FC) and do not wire the camera control.
Now, those two general tips will get you darn close! But what if your video still isn't perfect? Here's what you can do further. First, there are two types of issues. One is noise related, one is power related. Noise looks like clear lines through your video. Power issues look like black lines through your video. For a noise problem, a capacitor will work and you can add it now and ignore the tips below and go fly. For those not wanting to add a Cap or those with a power (black lines) issue, keep reading:
I have a noise (clear lines) issue: Follow steps 1 and 2 above. If still noisy (and you don't want to use a cap), then power your camera off of the same pads as your VTX. If this does not work, then your build requires a cap. Kind of a last resort is considering not using OSD or camera control and then wiring appropriately (depends, would you rather no Cap or no OSD in your build?). I have a power (black lines) issue: Your VTX is power hungry! This is a known thing with some VTXs, like the Mach 2 and the Unify series. They simply do not do well under regulated power. You can often confirm this by testing power levels. The issue will be worse at 800mw than 25mw. The only fix is to power your VTX directly off of the battery leads. If this does not remove the black lines, you have a defective VTX or a defective Camera. We'd bet it's the Camera that has gone bad before the VTX if you are taking a wild guess. But, if all is good then now you should either A) have clear video or B) have noise (clear lines now instead of black). If you have noise, refer to steps 1 and 2 above. If that does not fix the noise, then your build requires a capacitor.
