Arduino

Microcontroller boards compatible with the Arduino ecosystem, shields, and accessory modules enable quick prototyping of embedded systems. They span small, programmable controllers, USB-to-serial interfaces for programming and serial I/O, input/output expanders via shield form factors, and data logging or storage options. Projects range from sensor readouts and display dashboards to wireless or networked controllers.

Core capabilities include dependable USB connectivity, compatible voltage levels, clear pin mappings, and modular form factors that simplify stacking or compact builds. Many options prioritise easy integration with existing sketches, wide ecosystem support, and reliable operation in a range of environments. This category supports robotics, automation, sensing and monitoring, education, and other hands-on development where a compact, open-source hardware approach helps move ideas quickly to working prototypes.
