Data Sheet

Electrical Information
Operating Voltage (Vcc) 3.0V (2 x AA Batteries)
Max Current (All on-board devices and BBC micro:bit in use) 220mA
Number of External Pin Breakouts 2 x I2C/IO pin (each IO pin rated +3.3V @ 5mA )
:GAME Controller for the BBC micro:bit

Note on External Channels:
Care should be taken when using the external breakouts
for Pins 19 and 20 as GPIOs, as this can cause issues
with the I2C devices on the BBC micro:bit itself (e.g.
compass and accelerometer).
When using the 3.0V breakout pins, these should not
draw more than 80 mA in total, due to the current limit
of the power switch when combined with the BBC
micro:bit and on-board device usage.
