I reviewed the voltage regulator's data sheet and decided to change the incoming capacitor from 470µf to 680µf. An undersized capacitor could cause problems, but an oversized one won't hurt anything. Earlier, I thought the pinout was identical from all the regulators in the LM25 line, but that was not true, even though they use the same package. The footprint I chose was from the three-amp line. I also found an exact match for one of the capacitors, and for the other one, I matched it with another capacitor in the same line, but this one matched in the diameter portion of the part number.

I added a micro USB port, but instead of plugging it right into the 5V portion of the circuit, I decided to route it through both voltage regulators to ensure everything gets powered. After that step, I fleshed out the 5.0V regulator circuit and copied it over for the 3.3V system.
