ADC Board Rev 1

jkominek opened this issue · comments

Most of the fixes necessary for Rev 1 have been made and are covered under the Board Revision Notes.

  • Completion of #7
  • Bring out MCO1 and MCO2 on some test points, or at least confirm that the existing test points expose some timer pins. Goal is to make it convenient to measure the frequency stability of the built-in oscillators,
  • Triple check the transimpedance amplifier design in the analog half. @DigitalExegete agreed to help. :)
  • Final symbol/footprint/layout checks.

Past me was a genius, MCO1 and MCO2 are already available on test points. The same pins (PA8/TP26, PC9/TP25) also have some timer outputs on them.

c9634bf tweaked the edges of some of the copper pours around the analog area, and adjusted the routing on the NRST line.

been staring at the TIA forever. pretty sure we're good to go.
