4 2011-11-29 SparkFun <p> <strong>Description:</strong> This is essentially a ramped up version of our Ardumoto motor driver shield. For this monster shield we&#39;ve replaced the L298 H-bridge with a pair of VNH2SP30 full-bridge motor drivers. We&#39;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.</p> <p> <strong>Note:</strong> 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 30A system) However, when using the board at currents up to 6A the chips will barely become noticeably warm.</p> <p> <strong>Features:</strong></p> <ul> <li> Voltage max: 41V</li> <li> Maximum current rating: 30 A</li> <li> Current sensing available to Arduino analog pin</li> <li> MOSFET on-resistance: 19 m&Omega; (per leg)</li> <li> Maximum PWM frequency: 20 kHz</li> <li> Thermal Shutdown</li> <li> Undervoltage and Overvoltage shutdown</li> </ul> <p> <strong>Documents:</strong></p> <ul> <li> <a href="http://dlnmh9ip6v2uc.cloudfront.net/datasheets/Dev/Arduino/Shields/MonsterMoto-Shield-v12.pdf" target="_blank">Schematic</a></li> <li> <a href="http://dlnmh9ip6v2uc.cloudfront.net/datasheets/Dev/Arduino/Shields/MonsterMoto-Shield-v12.zip" target="_blank">Eagle Files</a></li> <li> <a href="http://dlnmh9ip6v2uc.cloudfront.net/datasheets/Dev/Arduino/Shields/10832.pdf" target="_blank">Datasheet</a> (VNH2SP30)</li> <li> <a href="http://dlnmh9ip6v2uc.cloudfront.net/datasheets/Dev/Arduino/Shields/MonsterMoto_Shield_Example.pde" target="_blank">Example Code</a></li> </ul> Monster Moto Shield http://www.sparkfun.com/products/10182 Motor Driver Monster High Power PWM 30A/Motor Motor Controller 2 5.5V - 16V OUTA1
