Description

PCF8574 x8 GPIO Expander with VGA/I2C Port

This breakout board is made for all of your pin-hungry Arduino / Linux projects! I decided to make it because I wanted to start learning about PCB design and wanted to have GPIO pins on my Linux laptop. It's a bit difficult to use it on Linux, so here is a tutorial on Arduino and Linux (the website is in WIP so please forgive me for its awful look). Here is a video showcasing the Linux part hooked up via the VGA port:
