Today I changed the power supply. I decided the STM 5VDC LDOs and my NXP 3.3v LDO were too large to hit the size I want for the PCB so I found new regulators and changed the circuit. Using Ti TPS79650DRBT for 5VDC and AVDD, and a Ti TPS73733QDRBRQ1 for the DVDD rail (3.3v). Expect updates to the git repo later this evening!
