SlushEngine: Model D Stepper Motor Driver

Regular price $229.00

The SlushEngine: Model D is the largest member of the SlushEngine ecosystem. This board uses state of the art motion engine technology that allows for simple and high performance motion integration and prototyping. This version of the SlushEngine can drive 7 stepper motors in total, 3 at 14 Amps and 4 at 5 Amps. The SlushEngine is different from other types of stepper drivers in that instead of toggling step and direction pins you can send it detailed motion commands. These give you control over precision motion, dynamic current settings, speed, acceleration and position monitoring.  

The SlushEngine is the simplest and most integrate Stepper motor solution available for embedded Linux systems. The SlushEngine is designed for pin compatibility with the Raspberry Pi. Just plug in the Raspberry Pi, install the software and motors will start moving. This model is host to other features such as analog IO and Industrial level outputs with PWM capability.

This SlushEngine was designed for use in more complex machines that required many motors to perform multiple tasks. This board can be used to drive our Remix 6 Axis 3D printed robot arm kit or any other device requiring up to 7 stepper motors.
