P8: General Purpose Digital IO

P8 is one of only two GPIO pins with no assigned function or useful alternate feature on the micro:bit. You can use this pin in your projects or designs for any purpose.

The Tech Specs

Outputs 0V to 0.3V when LOW
Outputs 2.7V to 3V when HIGH
Reads 0V to 0.9V as logic LOW
Reads 2.1V to 3V as logic HIGH
Can source/sink a maximum of 5mA
Tolerates -0.3V to 3.3V
11K - 16KOhm pull down/up resistance
A maximum of 3 pins can drive 5mA at any one time

Note, voltages are given for a micro:bit powered over USB.
