Description:

    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.

Features:

    Power supply: Max 16V.

    Maximum current rating: 30 A.

    Practical Continuous Current: 14 A.

    Current sensing available to Arduino analog pin.

    MOSFET on-resistance: 19 mΩ (per leg).

    Maximum PWM frequency: 20 kHz.
