hard:case for micro:bit
Pimoroni's Description of the hard:case for micro:bit
Turn your micro:bit into a wrist-mounted doohickey with this snazzy enclosure and slap band!
The enclosure securely houses your micro:bit, provides access to the two buttons, and even has a battery compartment to power your micro:bit on the move with two AAA batteries*.
There's also an on/off switch, access to the edge connector, and the whole thing snaps together without screws - swish!
Use the included wrist strap to mount it to your wrist, or use a keyring to attach it to your bag, or a lanyard to wear it round your neck.
Update: As of March 2018 we have no longer ship this with the spare four colour slap band
