Monster Moto Shield
Wondering what this product is about? Are you looking for a ramped version of the Ardumoto motor driver shield? We did this right here by some modifications and changes such as replacing the L298 H-bridge with a pair of VNH2SP30 full-bridge motor drivers; another thing we changed is adding a capability of driving a pair of high current motors by beefing up the support circuitry. Also, connecting larger gauge wire is now possible in an easy way since the VIN and motor out are pitched for our 5mm screw terminals, which made such a huge difference.
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.
