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.
• Maximum supply voltage: 16 V
• Minimal alert voltage: 5.5 V
• Maximum current / channel: 14 A
• Maximum current / spike channel: 30 A
• Maximum PWM Frequency: 20 kHz
• Protection against: overtemperature, overvoltage, undervoltage
The driver is ideal for controlling an average power engine.
To use the driver at full capacity, it is recommended to mount a radiator or cooler.
• Voltage max: 16 V
• 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
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.
