Swapping the included PDB with a Matek Systems PDB

So what happened is that I discovered the PDB that was included with my frame, the Martian II, actually is that it only is for the ESC, which I didn't even use because I am using a 4 in 1 ESC. The other problem is that my VTX, Tx and flight controller all use 5 volts, and the PDB does not have a voltage regulator.

At first I was getting work done preparing to connect the ESC to the flight controller, as you can see in the photo below, but I quickly realized that I would need a way to power 5V and the batteries I use are all 12V, 18V type batteries.

That's all I did this time!
