Monster Moto Shield VNH2SP30 Stepper Motor Driver High Current 30A Arduino

Dual VNH2SP30 Monster Moto Shield Module Stepper Motor Driver 30A16V For ArduinoProduct 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. *Over temperature protection, over-voltage and under-voltage protection.
