Arduino Shield “Monster Moto – Motor Driver 30A” (1 channel)
EGP 220
See other suppliers →Description
This is a knock-off of the SparkFun Monster Moto Shield, but it only supports a single motor, and doesn’t pass through the pins from an Arduino.UNO like the SparkFun board does. This board seems to be available from multiple sellers on EBay, Amazon, and direct-from-Asia sites like alibaba.com and dx.com (deal extreme). Search for “Monster Moto Shield” or “Mini Monster Moto Shield”, or “Mini VNH2SP30 Stepper Motor Driver” (or some variation thereof) to find it. 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
