Description: This is essentially a ramped up version of our Ardumoto motor driver shield. For this SparkFun Monster Moto 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.

So I ordered this to resolve a over heating issue using an arduino motor shield. Worked great. I can run my bot now using 2x12v dc motors without issue.
My initial order a capacitor popped from a bad unit and the team at sparkfun responded quickly and got me a replacement for my project and answered my setup questions.
I put it into a balancing robot, a 5ft tall balancing robot weighing about 60lbs. or more. Each motor draws around 6A under light load, locked rotor is probably in excess of the 30A rating, but should never happen. I did have to add a heat sink. The motors are quite powerful with very snappy response. After trying several options, including some designs of my own, this is the first drive amp to actually work in this project. Thank you SparkFun for a drive amp that can drive sizable motors.
