The Ardumoto Shield is a dual-motor controller for Arduino based on the L298 H-bridge. It can drive two DC motors at up to 2A per channel, making it an excellent platform for RC vehicles and small autonomous robots.
The board draws power from the Arduino's Vin line and includes blue and yellow LEDs to indicate active motor direction. All driver lines are diode-protected from back EMF.
Key Features
- L298 H-Bridge Driver – Two independent channels for driving up to two DC motors
- 2A Per Channel – Delivers up to 2A per motor (depends on power source)
- Direction Indicator LEDs – Blue and yellow LEDs show active motor direction
- Back EMF Protection – All driver lines are diode-protected
- Arduino Shield Form Factor – Plugs directly into Arduino boards
Ideal For
- Two-wheel-drive robot platforms
- RC vehicle control
- Small autonomous robots

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- Headers
- Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
- 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.
