We purchased motor driver DRV8301-69M Kit. We require more current. Your motor driver DRV8302-HC-C2 is rated 60VDC with full current at 40A. Can we modify DRV8301-69M Kit to the higher current in the field? We appreciate you support.

Hi Ignacio,
How much more current do you require? Both the firmware and hardware may need changes.

both kits actually support the same current sense scaling, +/-41.25A
this is set by the current divider circuits. You could increase this...probably to about +/-80 A but make sure you make the changes in the right place in software.
