This is essentially a ramped up version of Ardumoto motor driver . For this monster 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 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 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 in a high-current system) However, when using the board at currents up to 6A the will barely become noticeably warm. Voltage max: 16V Maximum current rating: 30 A Practical Continuous Current: 14 A Current sensing available to for analog pin MOSFET on-resistance: 19 mohm (per leg) Maximum PWM frequency: 20 kHz Thermal Shutdown Undervoltage and Overvoltage shutdown Colour:red Material:PCB Package Contents: 1 x VNH2SP30 Motor Drive Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
