# Power Shield (Arduino Compatible)

**Type:** Product page · **SKU:** DFR0105 · **Brand:** [DFRobot](https://core-electronics.com.au/brands/dfrobot-australia)
**Page:** https://core-electronics.com.au/power-shield-arduino-compatible.html ([markdown](https://core-electronics.com.au/power-shield-arduino-compatible.html.md))

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.

## Pricing

- **Price:** $28.90 (inc GST) — $26.27 AUD, exc GST
- **Quantity discounts:** 6+ $24.96 (exc GST) · 12+ $23.91 (exc GST)

## Availability & dispatch

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DFR0105:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/DFR0105:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## 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.
