This is an exciting new way to use your BBC micro:bit, without requiring crocodile clips which can be difficult for small people to use.
Also, this new approach allows the use of a single cable for most addons, instead of 3 crocodile clips.
Fittings for your micro:bit (micro:bit not included, unless selected)
Battery holder for 2xAA batteries permanently fitted (batteries not included)
Sturdy On/Off switch
Blue power indicator LED
White LEDs on all 3 inputs to show when active
The three Pins (Pin 0, Pin 1 and Pin 2) from the micro:bit are each brought to a new 3-pin connector as well as to a crocodile clip compatible terminal, so you can still use crocodile clips for your existing addons
Each new connector includes the signal as well as power and ground
