Do you have ideas for a project that moves? A robot, automatic dog door, moving platform? Whatever the project, the SparkFun Big Easy Driver kit is designed to help make it a reality.
Each Big Easy Driver can drive up to a max of 2A per phase of a bi-polar stepper motor. It is a chopper microstepping driver which defaults to 16 step microstepping mode. It can take a maximum motor drive voltage of around 30V, and includes on-board 5V/3.3V regulation, so only one supply is necessary. Although this board should be able to run most systems without active cooling while operating at 1.4-1.7A/phase, a heatsink is required for loads approaching 2A/phase.
To act as the brains of your project is a SparkFun RedBoard Qwiic microcontroller. The SparkFun RedBoard Qwiic can be programmed over a USB Micro-B cable using the Arduino IDE: Just plug in the board, select "Arduino UNO" from the board menu and you're ready to upload code. You can power the SparkFun RedBoard Qwiic over USB or through the barrel jack. The on-board power regulator can handle anything from 7 to 15VDC.
Also included in this kit are a 12V/5V (2A) power supply, reversible USB A to reversible micro-B cable, small heatsink, M/M jumper wires (30 pack), and 8x 3.5mm pitch (2-pin) screw terminals. The only thing you will need to provide yourself is a stepper motor (we've listed a few examples in the Hookup Guide below).
Note: The Big Easy Driver was designed by Brian Schmalz. A portion of each sale goes back to him for product support and continued development.
