April GPIO Options Quick Reference Chart

Many developers use the imp001 card and the April breakout board (together forming the standard Electric Imp Developer Kit) as the basis for prototype hardware projects. Click on the thumbnail below to download a chart showing April’s GPIO pins and the extra functionality they offer. Print it out and keep on the wall in your workshop or close at hand for easy reference. You can also use it as desktop wallpaper on your computer for at-a-glance access while you’re working in the Electric Imp IDE.
