The Elecfreaks Wonder Building Kit is a box jam-packed with creative building brick projects for your BBC micro:bit (not included) and the included sensors and components you need for 32 different projects! Learn how to code in the most fun and engaging way possible - by creating cool building brick projects that move and react using code YOU designed!

Including the popular 'Wukong' micro:bit expansion/driver board, over 400 building bricks, a range of different electronic sensors (line-following sensor, obstacle and water level), motors, servos, cables, fixings and more - it's a big ol' box of fun for micro:bit fans new and old!

The Wukong expansion board has a built-in 400mAh battery supporting 20-minute fast charging and can run a project for ~40 minutes (depending on the project and usage).
