This VNH2SP30 Monster Moto Driver Shield has NH3SP30 chip which enables it to drive one DC motor. It has an extremely high current capacity of 14A per channel (peak of 30A for few seconds). The thermal heating is minimal uptill 4 to 5 amps. However it would need thermal dissipation device like heat sink or cooling fan for higher currents.
Also the difference in the standard Arduino Motor shield and Monster Motor shield is the change in the driving IC. In the standard Arduino Motor shield the IC used is L298 H bridge IC which has a current capacity of 1 A which is replaced by the VNH3DP30 chip with a 14A conitnuous current capacity with heat dissipation devices installed. This motor driver also has a thermal shutdown function possible as the thermal output is provided on the analog pin of arduino.
