Driving stepper motors is a perfect example: you can grab a cheap controller board, hook it up to a microcontroller, and the rest is essentially just software.

Even first-time users can get a stepper motor moving as commanded in 30 min or less. Commands can be issued from any serial terminal program or from the EZ Stepper Windows program, but the EZHR17EN ...

Packaged in a single multi-chip module, the integrated driver/amplifier achieves the lowest power dissipation currently available for a 4A stepper motor driver. With an Rds (on) of 65mΩ, the TMC2660 ...

Instead of using a latch and the Arduino’s PWM pins, we have a fully-dedicated PWM driver chip onboard. This chip handles all the motor and speed controls over I2C.

The new DC and Stepper Motor HAT for Raspberry Pi is now available to purchase for $22.50 and has been designed to allow makers to construct their robotic dreams ...
