Stepper Board for X27 stepper motor

I’ve been working on the X27 168 stepper controllers to find that there is no need to make a board for these steppers.

They can be connected directly to an I/O board with the following two limitations:
- It won’t be valid for high speed gauges (i.e Altimeter). This is because the motor has a 1:180 gear ratio and needs 6 steps for one motor turn. That gives us 1080 steps for a 360º dial.
- It will only valid for gauges with equally distributed scale.

Good thing is that we can use them for Cabin Press, EPU Fuel and Hyd Press gauges and even Clock and Fuel Gauge using the X40.879 which comes with a double coaxial independent shafts.
