As you might recall, the PDB I used was a Matek Systems PDB with built-in voltage regulators for 5V and 12V. All the components I bought were 5V components, and thus I would have to fit everything onto the 5V solder pad. Something I didn't do was use the ground for the 12V, as you'll see: In addition, I also did not use any of the ESC solder pads for the PDB, thus the only thing it was used for was the 5V pad. In hindsight, if a cheap voltage regulator existed, I might have used it because it might have provided more space to solder things onto it as well as additional mounting options, but alas that is not what I did. The photo I have placed below is the original photo of the PDB and where I decided to mount it. As you can see, I did not actually mount it due to the lack of space, but I still put screws in because I plan to mount it to the flight controller, and just let it rest against the top of the frame. Underneath you can see the bare ESC, since I decided to remov...
