Kiss PDB
This is a power distribution board that has current and voltage sensing plus a 5V BEC. Below it is shows with a JST-SH cable attached to the power / voltage lines that is easy to connect to Sparky or Sparky2. It also has a servo cable attached with 5V BEC circuit.
The power and ground spacing are lined up with KISS ESCs but can be wired to anything else.
The ESC control lines can be routed through the PDB if that is convenient. The pins labeled 1-4 are connected to the signal lines on the pads ESC 1-4. Then you can just use two servo cables to connect all the PWM and power lines to the flight controller.
