The Elecrow CrowPi 3 is a kit that provides a bunch of tools and resources to help young people develop computer science skills. The kit is about the size of a small, but chunky laptop, measuring 285 x 185 x 38mm (11.2" x 7.3" x 1.5"). But instead of a large display and keyboard, it has a small screen, a bunch of sensors, and support for a wide range of electronic components.
