  1. More via stitching between GND planes.

    hzeller committed Oct 30, 2017
    Mostly to heatsink ULN2003, but also in other places to reduce
    impedance.

  1. More cooling for ULN2003

    hzeller committed Oct 29, 2017
    o Connect unused pins to a GND copper plane for slightly better
      heat distribution (in any case, we are well within ratings
      of the chip; the sum of all currents is never more than 500mA).
  2. Connect USB output to SYS 5V

    hzeller committed Oct 29, 2017
    o SYS 5V has a cleaner switch-on transition than the raw DC/DC out.

  1. Remove unneccessary inner layers.

    hzeller committed Oct 8, 2017
    o There were inner layers left-over from basing this on the PocketBeagle.
      Just keep Top/Bottom.
    o Remove leftover text from inner layers.
  2. Update cape rendering.

  1. Improve silkscreen.

    hzeller committed Oct 5, 2017
    o Label signals directly on header for easier measurements.
    o Arrange partially obstructed component labels.
  2. Intermediate state: initial display and USB connector.

    hzeller committed Oct 5, 2017
    o Add flat flex connector to drive a simple SPI-based display.
    o Try to cram a vertial USB connector onto the board to be able
      to have a wifi dongle.

  1. Simplyfy photo diode sync input.

    hzeller committed Oct 1, 2017
    o The 74LVC14 inputs are sufficiently high impedance that we
      can directly connect the photo input.
    o Also: switch to JST PH 2mm connectors for laser output.

  1. Fix wrong connection to stepper connector.

    hzeller committed Sep 30, 2017
    o common is not the center tap, but Pin5
    o Also some more labelling (e.g. adding RX/TX)
  2. Move component labels for better readability.

    hzeller committed Sep 30, 2017
    Also add signal labels on the PocketBeagle header for easier testpoint
    finding.
