Description: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- 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 in a high-current system) However, when using the board at currents up to 6A the chips will barely become noticeably warm.Voltage max: 16VMaximum current rating: 30 APractical Continuous Current: 14 ACurrent sensing available to for analog pinMOSFET on-resistance: 19 mohm (per leg)Maximum PWM frequency: 20 kHzThermal ShutdownUndervoltage and Overvoltage shutdownColour:redMaterial:PCBPackage Contents:1 x VNH2SP30 Motor Drive ModuleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
