## Description

Introduction

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.
