The ProtoWuino is an "Arduino compatible" prototyping board we designed for making custom circuit shields. You can plug it into any Arduino or compatible single board computer, and solder on DIP, SOIC and 0603 sized components and wires to make your custom circuit. Once you've got that going, use CircuitMaker to fully customize your production PCB layout!

Many users have been given one of these (sometimes more) at Maker Faire and other events. Send us a comment and let us know what you've made with it!
