So I found the Trinamic Step Stick TMC2100 driver on Digikey for a great price. I snagged a few for my desktop build. Figured I would share with you guys wanting genuine Trinamic Step Sticks at a great price.
Aha, you found the $8.06 treasure trove. I got a few myself for testing.
Wait wait wait. Desktop build? Is there another machine coming?
There is. It is an Ultimaker style gantry build using Hiwin MG 9mm rails instead of the XXLMUU linear rails… We have an Ultimaker 2+ at work and I am very impressed with it.
Can we talk control board choices for it? 
Azteeg X5. The one I am using for my large coreXY has been flawless and Smoothieware has been excellent as well.
GT or Mini?
Probably just the regular mini since I will not need any of the added features of the GT.
@raykholo Here is the current design.
Wait… Are these a drop in replacement for like ramps style boards?
@rubin_kingma They appear to be. I received them in the mail today. They are the step stick you would get if you ordered straight from Watterort (sp?). They do come with the pin headers loose in the bags so you just have to solder the pin headers to the boards. You will also need to order some heatsinks if you dont already have some.
