TinyCircuits is a manufacturer of miniature open-source electronic components that enable users to develop their own compact electronic projects. Its flagship product is the TinyDuino platform—an Arduino-compatible system roughly the size of a U.S. quarter coin. Designed with full modularity, the TinyDuino platform functions like micro-scale electronic LEGOs, allowing users to effortlessly integrate advanced capabilities—such as GPS, Wi-Fi, motor control, or graphical displays—into their projects simply by connecting expandable modules known as TinyShields.
