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:
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:

The table below shows the intended purpose of each of the pads on the board. Detailed instructions for wiring up the board are later in the manual.
TOP OF BOARD
Battery voltage negative, wired to ESC.
Battery voltage positive, wired to ESC.
S1, S2, S3, S4
Motor signal outputs 1-4.
Serial receiver (SBUS, iBus, SpekSat) input. UART1. Can be used with both inverted and non-inverted protocols, but iBus telemetry and SpekSat binding don’t work on this pad. Can also be used for ESC Telemetry if you’re freaky like that.
SmartPort telemetry input (inverted) UART3.
5v or 3.3v output for receiver. Use solder bridge on underside of board to select voltage.
7.6v filtered output for FPV camera and vTX. Max 1.2 amps.
UART6 receive pad. Use this for non-inverted receiver input such as iBus or SpekSat. iBus telemetry and SpekSat binding work on this pad. Can also be used for other receive functions like ESC telemetry.
Video signal input from FPV camera.
FPV Camera OSD Menu Remote Control function. Connect to camera OSD input pin.
Programmable LED output pin. Usable with Betaflight LEDStrip feature. Also, can be reassigned to SoftSerial via Betaflight resource remapping feature to provide one additional UART
TX4 / RX4
UART4 TX and RX pads. TX4 is primarily intended for use with vTX remote control function such as SmartAudio or Tramp Telemetry. UART4 is the only one UART on the board with both TX and RX pads available. If UART4 is needed for some other purpose, reassign LED pad to SoftSerial and use vTX remote control that way.
Negative leg of piezo buzzer.
Positive leg of piezo buzzer.
Video out to FPV video transmitter.
BOTTOM OF BOARD
5v output for accessory devices. Max 1.2 amps total across all 5v pads.
Main battery lead positive wire.
Main battery lead negative wire.
Solder bridge for selecting 5v or 3.3v output to receiver pad on top of board.
1.Amazing board for beginner
My wife bought this board as a Christmas present for my first fpv build after I had already gotten the f3 v4 and I couldn't be happier that she did. Build quality is great, pads are large and clearly marked and the guide is propably the best there is. Sure Chinese copies are cheaper but with this board you don't have to guess or try to find buil
