Our old bat:bit was great but sometimes the acrylic could crack during assembly or the pins wouldn't quite line up with the test pads on the rear. The bat:bit 3 is our solution!
Simply slide the micro:bit into the connector on the bat:bit 3 and insert 2 AA batteries and you are good to go!
The bat:bit 3 covers the rear of the micro:bit protecting the test pads from accidental shorts while leaving the reset button and USB connector accessible.
We have all of the micro:bits edge connector broken out to another edge connector so you can still use most your existing micro:bit add-ons.
we even have a handy little power switch on the right of the board, up is off and down is on!
Sadly due to the size of AA batteries the bat:bit 3 won’t fit in to the standard micro:pixel.
