What is it?

This is a breadboardable GPIO to VGA adapter. It was designed to work specifically with the Raspberry Pi Pico, but it will work with any microcontroller that can generate a VGA output using a simple resistor DAC at up to 5 bits per color.

Why did you make it?

The Raspberry Pi Foundation published example circuits for use with the Raspberry Pi Pico module, and many manufacturers built boards will all of the circuits on a single board. If you don't need all of them, this module will save you a bit of coin.

I love creating old-school games, and outputting graphics to things like TVs and VGA have always been a fun way to output those games.

What makes it special?

This is an inexpensive solution for connecting to any monitor with a VGA port. Although there are other solutions out there, this one is simple, generic, and inexpensive. It will work with nearly any resistor-based example circuit published on the internet.
