My VGA clock design is the world’s first certified open source hardware down to the chip level.

Unfortunately the MPW1 chips were very hard to use and the new ones have a different pinout and footprint. I’ve been using the clock design as a test project for all the Tiny Tapeout chips past TT03.

To test the new mux structure introduced at TT04, we ran an experimental TT3.5 chip. The chips are back and the clock works as expected (phew!)

As we have a hundred chips but no customers, I’ve decided to create a VGA PMOD that turns the dev board into a dedicated clock.

More information and resources can be found here: https://bit.ly/vga-asic-clock.

The new PCB is here: https://github.com/tinytapeout/tt-vga-clock-pmod.

To buy a kit head to the Tiny Tapeout store.

For every kit sold, I will donate $100 to OSHWA.
