The first revision of the pico-vga hardware and PCB design. Releasing so this can be saved separately and so I can start work on revision 2.

Issues with this board rev:

  • The CD4072B chips (dual quad-input OR gate) have VCC and GND reversed on the PCB. Therefore, when assembled and plugged in, the Pico does not turn on. The board heats up quickly. As a result, none of the controller logic hardware works (since the OR gates are a part of the chain to connect them to the Pico)
  • The USB-C connectors are incredibly hard to solder, especially by hand. These will be replaced with something better in rev 2.
  • 0603 footprints for resistors and caps are hard to work with, so these will be replaced with 0805's next time.
