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 3.3V breakout pins, these should not
draw more than 50mA each, or 100 mA in total, due to
the current limit of the voltage regulator.
