I made for myself two testboard, one for the standart Pololu stepper driver and one for TMC stepper driver with SPI. I use them to test various stuff. They can be used to prototype. They have an switching 5v power regulator, which powers a linear 3.3v power regulator. They don't have a mcu on board, instead you hook any flavor of mcu you want (and test) with jumpers on it. For some of you they can be usefull, or not.
There is a small error on the boards. I started to count the extruder stepper with the number one, not zero.
