ADC Board Rev 1 bringup

- Check adjusted power supply filtration.
- Check MCP120 chip.
- Check 2V regulator.
- Check transimpedance amplifiers.
- Check JTAG header works right now.
- Check RS485 wiring
- Should put a microcontroller on to ensure that some of the rearranged digital lines are ok (the UART in particular)
We'll want the new TIA circuits for testing/writing analog processing code going forward.
Hmm not sure what I meant by "adjusted power supply filtration". Using surface mount caps? Guess I can compare old & new +3.3V lines on the scope.
+5V and +3.3V looked pristine when I was checking the MCP120 at power-on. Calling that good enough.
UART3 to RS485 works fine.
