Here’s a tutorial on the TOS-100 Arduino stepper driver shield.
The TOS-100 is an Arduino compatible Shield capable of driving one stepper motor up to to 1.7A that utilizes the Trinamic Motion Control TMC260 motor driver chip. For added compatibility with other arduino shields, the TOS-100 allows you to choose nearly any pin for any signal.
Pink PCB! .. Thats a first for me.
I was impressed with the performance of the stepper motor with this driver.
