Description

VNH2SP30-based Triple channel DC Motor control board with reverse input voltage protection and output short circuit protection. Should work (hopefully) in full VNH2SP30 supply voltage range.

The PCB should be placed on the heatsink for optimal performance and stability.

This project is UNTESTED and UNPROVED

Input resistor network layout far from optimal and done with the eyes closed...
