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.

Features:

• Voltage 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

• Thermal Shutdown

• Undervoltage and Overvoltage shutdown
