Pin 10 is not PWM capable. Pins 0-9 are, and they also have internal pullups.

Pin 0, 1, and 2 must not be held low at boot. Be careful not to attach pull down resistors to them (pull-ups are fine) unless they are only active after power up. Pulling P1 to GND will enter safe mode (if configured to do so) allowing for recovery from bad code and allowing for the Oak to be reconfigured. Pulling P2 to GND will put the Oak in firmware programming mode, allowing you to reset the Oaks firmware in those unfortunate times where something has gone majorly wrong!

Pin 6 must not be held high at boot. Be careful not to attach pull up resistors to it (pull-downs are fine) unless they are only active after power up.

There is only one analog input capable pin, A0.
