Pedal Board Rev 1

jkominek opened this issue · comments

  • Rev0 is huuuge. It can be made narrower. Maybe?
  • Push the TRS jacks back slightly, so the mounting flange on the face of the jack lines up with the PCB. Some quick measurements suggest that "slightly" is 2.1 to 2.3mm in this case.
  • Ensure that the 40mm spaced mounting holes have a setback from the board edge consistent with our other panel-mount boards. Ensure there is enough space around them for whatever mechanical solution will hold them to the panel.
  • The TRS jack footprint has an error, in that what should be the silkscreen outline is actually a line on the solder mask exclusion layer. So what initially appears to be a nice outline is actually exposed (and HASL'd) copper.

Noncritical

  • Bring the I2C bus out to a 0.100" header.

Changes made in bbeeac4

  • Made it narrower, but had to expand the space between mounting holes.
  • Moved the jacks back 2.3mm.
  • 10mm to board edge, 5mm clearance on the inside of the board, 7.5mm clearance on either side
  • Fixed the outline to be silkscreen, not a hole in the mask
  • Added I2C bus header
  • Made nice little three pad footprints for spots where you need a pull up or a pull down.
  • Drastically increased the space between the Qwiic headers
  • On the pedal jacks, the signal is really on the Tip, not the ring where I had it. Not sure what I was thinking.
