Trinamic TMC2208 Eval-Kit

Trinamic created the TMC2208 driver for two-phase bipolar stepper motors. It integrates microPlyer™ for smooth running 256 microstep interpolation, and stealthChop2™ for silent motor operation such as a 3D printer. Lastly, it uses spreadCycle™ as a highly dynamic motor control chopper. For exact current rating you can use an external sense resistor, or it has its own internal sense resistor option.

When you first connect the device to your laptop, you will have a flashing green light and possibly a red error light. The error light will come on if you are not connected to an external power supply via the connector on the evaluation board itself. This board will not be able to drive a motor by just the USB power. The external power supply is not sold with the kit and will need to be purchased separately. Trinamic recommends using an adjustable power supply around 24 VDC/1 A output. The maximum current the board can deliver is 1.2 A, so you should select a stepper motor that has a maximum phase current of around 1 A.
