Hi everyone! I am part of an team designing autonomous drones. Although not expert circuit designers, we intend to make our custom power distribution board for a micro drone. I made the design in KiCad and would love to hear your thoughts on it!
The board is supposed to supply :
20A at 17.4V to a 4in1 ESC (powering 4 BLDC motors) max.
5.3V to flight controller at 2.5A max.
12V to video transmission system at 1A max.
Before buying the components, requesting a review of the work.
Unfortunately the site only allows me to upload one embedded file, so I am putting everything into a google drive folder. Sorry for the inconvenience

The folder has -

For the prototype and testing stage I plan to run it at low currents and use 1oz copper on all four layers as it’s cheaper.
Some of the things that I am eager to have reviews on:
- Buck converter layouts on front cu.
- Current sensor layout on front cu.
- Effectiveness of the 330uF electrolytic capacitor against hot plugging and motor disturbances.
Thank you!
