TMC2209 Stepper Motor Driver IC

Stepper Motors are the workhorses of several industrial, robotic as well as consumer / office electronics. It rotates in ‘steps’ and helps you achieve a precise positioning of the motor’s shaft. They are also brushless motors but unlike BLDC Motors, the drive electronics for a stepper motor is very simple. Speaking of drives, the TMC2209 … Read more
