DC Motor Driver VNH2SP30 (30A Peak – 15A Continuous)

This is a high power dc motor driver based on VNH2SP30 chip from ST.  It is designed for high power dc motor control applications with peak current up to 30A and continuous current of 14A.

The module is easy to use with arduino or any other microcontroller. The motor driver also have thermal shutdown capability for  protection of overheating, it also have current sensing and overvoltage protection. It is very similar to sparkfun Monester moto driver, the only difference is that this module drive only one motor at a time.
