Dual VNH2SP30 Monster Moto Shield Module Stepper Motor Driver 30A16V For UNO
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.

Maximum current rating: 30 A.
Practical Continuous Current: 14 A.
Current sensing available to UNO analog pin.
MOSFET on-resistance: 19 m (per leg).
Maximum PWM frequency: 20 kHz.
Over temperature protection, over-voltage and under-voltage protection.
