SparkFun DEV-10182 Monster Moto Shield
This is essentially a ramped up version of our Ardumoto motor driver shield. For this monster shield we’ve replaced the L298 H-bridge with a pair of VNH2SP30 full-bridge motor drivers. We’ve also beefed up the support circuitry so this board is capable of driving a pair of high-current motors! The VIN and motor out are pitched for our 5mm screw terminals (not included), making it easy to connect larger gauge wires.
Note: When using this board in extreme high-demand applications it may be necessary to improve thermal performance with a heat-sink or fan and to solder the wires directly to the board instead of using a screw terminal (in addition to the myriad other complications present in a high-current system) However, when using the board at currents up to 6A the chips will barely become noticeably warm.

This Monster Moto shiled is a great bit of kit, the drivers have incredible drive capabilities.
Before purchasing the Monster Moto shield I initially purchased what I thought was one on eBay, it turned out to be a clone, and a very bad one at that. neither of the drivers worked and I subsequently found lots of people with the same issue on-line.. Beware, buy cheap buy twice!
