user1564: I recently bought Adafruit's motor shield v2 only to find out it can only support upto 12v.
So I'm on the look out for another shield & found this one 
Arduino Dual L6470 Stepper Motor Shield
I have an Arduino Mega & the documentation says it is fully compatible with the UNO.
Will there an issue using this shield with a Mega? Or if anyone else can point me at a decent stepper controller?

user4143: That is an SPI based device, and it doesn't use the (now considered standard) 6-pin ICSP header for SPI.
Therefore it will only directly work on boards that have the SPI pins available on pins 10-13 of the digital headers.
To use it with other boards you will need to manually route the SPI pins to the right places using wires.
