The Monster Motor Controller Shield For Arduino (14A, 5.5-16V) is essentially a ramped up version of Sparkfun's Ardumoto motor driver shield.
For this monster shield maufacturer has replaced the L298 H-bridge with a pair of VNH2SP30 full-bridge motor drivers. Manufacturer has also beefed up the support circuitry so this board is capable of driving a pair of high-current motors.
• Maximum current rating: 30A
• Maximum voltage: 16V
• MOSFET on-resistance: 19mOhm (per leg)
• Maximum PWM frequency: 20kHz
• Undervoltage and overvoltage shutdown
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. However, when using the board at currents up to 6A the chips will barely become noticeably warm.
