In stock, ready to ship.
We are now US distributors of a Stepper Motor Driver based on a Trinamic TMC2100 and created by Waterott Electronic. Much smoother control, up to 256x micro stepping, quieter, sometimes nearly silent stepper operation. Be sure to read the documentation! Currently shipping v2 of the standard version.
Comes in both kit and pre-assembled forms. Kit forms comes with pin headers you must solder in place, pre-assembled comes with the pinheaders already installed.
