Description of the article:
This is essentially an enlarged version of our ardumoto engine driver’s shield.
For this monster shield we replaced the l298 h-bridge with a pair of vnh2sp30 full bridge engine drivers.
We have also reinforced the support circuits so that this board is capable of driving a pair of high-current motors!
The vin and motor out are launched to our 5mm screw terminals (not included), making it easier to connect larger caliber wires.
When using this board in extreme high-demand applications, it may be necessary to improve thermal performance with a heatsink or fan and solder the wires directly to the board instead of using a screw terminal (in addition to the myriad other complications present in a system high current) However, when using the board in currents up to 6a, the chips barely become visibly hot.
