Gumstix Pi Stepper HAT
Precision Stepper Motor Control with 1/32 microstep accuracy on a Raspberry Pi® HAT. An ideal addition for robotics, IP camera, or printer projects.
Need rotational accuracy below a tenth of a degree? The Gumstix Pi Stepper HAT delivers. The TI DRV8846, a 4 - 18V, 1.4A stepper motor driver with 1/32 microstepping, provides high-resolution control of 4-wire stepper motors to any Raspberry Pi®.
With a 1.8°/step motor, the Gumstix Pi Stepper HAT can divide a full 360° rotation into 6400 distinct positions for surgically precise motion control. Variable torque and decay rates, as well as adaptive blanking, make this stepper motor driver a versatile robotics component.
For more information on the TI DRV8846, download the reference manual here.
Add the Stepper Motor Driver module to your design or create your own Raspberry Pi HAT in Geppetto D2O.
