The Arduino-based evaluation kit (EVK) is said to supports the evaluation of ROHM Semiconductor’s motor driver devices and enables, facilitates and accelerates customers’ developments. Designed as a ...

Leveraging the Trinamic TMC2208 stepper motor driver gives Ethersweep silky smooth and quiet motor control, which could be very important for some applications.

Rather than having the host Pi communicate directly with the stepper drivers, the 3+Pi features an onboard STM32F302CBT6 that handles the actual motor control.
