Compass PCB prototype 02

Building on the Compass PCB prototype 01 I’ve updated the PCB so that I can install the 16 boards easier, along with doing some little things to reduce the amount of wires which will need to run this array.

LED PCB v0.4I created a Ground Bus which I can solder to Board 01 from the Arduino GND and then daisy chain the next 15 together, so I get rid of 15 unnecessary wires. I then moved the +5v feed (which will come from the shift registers) to the top, so I can solder wire, straight, or angled headers depending on what I decide. Lastly, I moved the support holes to the center so that I will be able to flip the board one way or another to install it. This will allow me to manage the 16 wires which go back to the shift registers in a logical way. How I will do that is for another day, at least I know I have options, and I’m giving myself some flexibility here.
