Most project of Arduino may need more than two voltage supply. When feed with from 4.5-35V, this arduino 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 arduino power supply 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.
SPECIFICATIONS
- Supply voltage:4.5-35V
- Output voltage:1.25-12V
- Output current: 2A (3A peak)
- Max output power: 15W 3A@5V
- Efficiency:90%

Jargon buster
Plain-language definitions for the technical terms used above.
- servo
- A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
