Z-ranger IO pin

[bpospeck]

Hello,

I've been looking into the new Z-ranger a little bit and notice on the wiki that it uses the i2c pins as well as one of the GPIO. I have attempted looking through "vl53l0x.c" to figure what the IO pin is being used for. I did not see anything, but I could easily have missed something.

I'm hoping that the IO pin is optional for the Z-ranger because I've been working on adding 2 external motors to the Crazyflie so that it can also roll on the ground. Each motor requires 2 GPIO pins, so that leaves no extras. Unless the IO pins are easily used from NRF51? Then that would give me extra IO space.

The extra IO is not used and not required. It is not connected by default, there is a solder bridge on the PCB in case someone would want to use it.

So there is no problem for you to use this IO for something else.
