RTFDS! j/k 
Your motor driver bible here: http://www.toshiba.com/taec/components2/Datasheet_Sync//261/27197.pdf
Just fyi
I got that datasheet from Digikey but it’s also at the Pololu page you linked to. It’s under the “Useful links” tabs in the item description.
Thank you very much! I’ll
Thank you very much! I’ll have a look at it. +_-
Yeah same thing on my nano
Yeah same thing on my nano sumo (mine is from sparkfun http://www.sparkfun.com/products/9457)
Ok here we go…
AO1, AO2, BO1, and BO2 are your outputs that wire to your motor (motor A and motor B)
AIN1 and AIN2 are your motor inputs for motor A (high & low = one direction, low & high = the other direction)
BIN1 and BIN2 same thing as above but for motor B
PWMA is for pulse width modulating motor A to control the speed ( do not have to use this if you do not want to but needs to be pulled high for movement)
PWMB same thing as above but for motor B
I just pull standby high (low = standby mode and idk what that means)
“Power supply voltage: VM=15V max, VCC=2.7-5.5V”

Oh ok thanks. It was that
Oh ok thanks. It was that simple XD
Based on the silkscreen on the back of the board,
you missed VMOT. VMOT is the forward voltage that must be provided for the motors, which is as you state at the bottom of your post as 15V max.
I would only hazard a guess that standby being enabled would cut the current draw of a circuit when you don’t need to drive a/the motor/s (pull the pin low and the chip goes into low power mode that just keeps it awake rather than active and supplying current to the high voltage internals).
