43 Amp Arduino Motor shield, the Arc-Controller

The Arc-Controller is here to give power to the Maker by bring high Amp motor control to your projects.

We are Makers. Our goal at Arc-Robotics is to give power to the Makers. We believe by combining your imagination with the right tools and equipment, you can change the world. That’s what we are here for; to give you the tools, tutorials, and resources to make it happen.


There have been a lot of amazing projects come out of the Maker revolution, however, many are limited by the capability of their motor controller. We want to change that. The Arc-Controller is a bridge to bring high Amp motor control to your projects, up to 43 amps with a heat sink. It is capable of variable speed and direction control over a single Stepper Motor or two DC motors, because when do you only need one motor.

The Arc-Controller is compatible with about any Arduino, or other micro controller such as Raspberry Pi. It runs an ATMega328, and is user programmable via the Arduino IDE. Thanks to the ATMega the Arc Controller can run as a standalone micro controller or be slaved by any other device. Giving Makers the ability to push the limits of what has been done and change the power to change the world.

The Arc-Controller is American Made goodness. It will be manufactured by Advanced Circuits. Advanced Circuits is the third largest PCB board suppliers in North America and is very reliable. To insure quality we will individuality test them and have test sketches run to test functionality before they are shipped.
