The ring:bit car is a DIY smart car which is based on the micro:bit and ring:bit. The ring:bit has extended 3 channels of GPIO, for which 2 are used for driving servos and one channel of GPIO is undefined.

This is a great product for kids and beginners who are looking to get into programming or electronics, the shell can be assembled by hand while the micro:bit's "blocky" programming environment is brilliant for starting to learn Python and JavaScript meeting the needs and levels of all learners. 

Note: This kid does not contain a micro:bit or batteries.
