TinyCircuits

TinyCircuits is a maker of tiny open source electronics that let users create their own miniature electronic projects. The main product line is the TinyDuino platform - an Arduino compatible platform the size of a US Quarter. The TinyDuino platform is completely modular and works like tiny electronic LEGOs, so complex functions, like GPS, Wi-Fi, motor control, or graphics displays can easily be added to projects just by plugging the expandable modules (called TinyShields).
