Most project of Arduino may need more than two voltage supply. When feed with from 4.5-35V, this power shield able to provide a voltage range from 1.25-12V with 3A peak current. Ideal for servo control and other non-standard components. With this shield, your Arduino now have one power supply for all.
It has be build-in voltage measuring function which mapping the output voltage to Arduino analog pin 0. It can be controlled by Arduino digital Pin13 to switch on/off.
If you are interested in Internet of Things (IoT) or M2M projects check our open source sensor platform Waspmote which counts with more than 100 sensors available to use 'off the shelf', a complete API with hundreds of ready to use codes and a low consumption mode of just 0.7µA to ensure years of battery life.
