In my quest to keep wiring neat (which it is not at this time), I wanted to create a board that would help minimize the amount of wiring needed.
So I create a Power Distribution board that will take all servo inputs from 2 EZ-B v4/2’s and then isolate and output the signal wire to the EZ-B’s. The power will be handled by the PDB.
The PDB will also have two LED’s allowing me to see that the PDB is receiving power to each side. There will also be a 4 pin header that is for Ground so that the servos are running from the same ground, 2 Pins can be routed to each EZ-B. So now instead of having power spliters/headers all over the place all power is handled right here on this board. So all the ground and power wires from the servos can plug straight in here. Only 1 wire now needs to go from here to the EZ-B Robot Controllers, this significantly lowers the amount of wiring needed. Each Robot controller can be individually power and fused. This also cuts the amperage draw down as each side only handles half the servo load.
Eventually the goal will be to make one Main Board to handle the entire robot. But for now I am doing it in small phases until I have everything the way that I want it to be.
