I need to control an Stepper motor <http://www.pololu.com/product/1200>with 
the IOIO-OTG and the DRV8834 breakout 
board<http://www.pololu.com/product/2134>.  
However, I want to check with this group that I'm connecting it correctly 
to the IOIO.  Ytai once mentioned that for his ShoeBot project, he 
connected the IOIO Vin to the driver <http://www.pololu.com/product/1182>Vmot 
pin to supply power to the motor.  That said, I have a 7.4V 
Lipo 
Battery<http://www.hobbypartz.com/98p-50c-5000-2s1p-hardcase-2222-direct.html>(5000mAh)
 to supply power to the IOIO and here is how I think the pins 
should be connected.

*IOIO Pin               DRV8834 Pin*
Vin          ------>      Vmot
GND       ------>      GND
P3           ------>      STEP
P23         ------>      DIR
5V           ------>     FAULT
GND       ------>      GND

I'm not sure if the last 2 are required since according to 
Pololu<http://www.pololu.com/product/2134>, 
"the DRV8834 does not require a logic supply".

DRV8834 pins A2 ,A1, B2, and B1 connect to the motor, but I don't know if I 
need to use M0 and M1 though.

Any comment or correction will be appreciated!
