This page is devoted for the project Gen7Tm, which aims to replace expensive stepper motor drivers from Pololu company to a cheaper option. The material is participating in the contest "Race to Bottom".

I like Gen7T design, based on TB6560AHQ, from Bryanandaimee, but there are difficulties routing a single sided board with these chips. I also like the modular system of Pololu drivers. So I wanted to combine the two ideas into one solution. At the same time as the controller board, and module boards remain one-sided and with through hole installation.
Note: The enable line is inverted from the way it works on the Pololu drivers so this MUST be changed in firmware before powering on the 12V to the drivers, otherwise the smoke will escape.
