Colorful pin headers

While waiting for the female pin headers and a few small components to arrive, I partially populated one of the messed up boards to get an impression on how the final board will look. The result is colorful :)

White pins are signal pins, connecting directly to the Nano. Red pins connect to the 5V rail. Yellow to the 3.3V rail. Black pins are ground. Blue pins connect directly to the nRF and turquoise-ish pins are used for whatever is left. Hopefully this will mistakes during wiring. The remaining four rows of connections will receive a 15 pin female header. The inner two rows receive the Nano, while the outer two rows can be used to connect jumper wires. The three large holes were supposed to hold a DC jack connector.
