LEDs: The STOP:bit has 3 10mm LEDs (1 Red, 1
Yellow, 1 Green). Each of these LEDs is driven from
one of the BBC micro:bit IO pins. The table to the
right gives the connections between the LEDs and the
IO pins.

Power: Power is supplied from the BBC micro:bit connections

Connection: x5 M3 countersunk screws allow the

user to bolt the STOP:bit onto the BBC micro:bit.
Crocodile clips also can be used between the pads
on the STOP:bit and the matching pads on the BBC
micro:bit.

Stand: The bottom section of the STOP:bit PCB is
designed to break off and then slot together with
the main PCB to form a stable cross base.

Software: Custom MAKECODE blocks
have been created. They are available at:

It is also possible to use the ‘digital write
pin’ block to operate the LEDs.
