2 layer board of 2.99x2.10 inches (75.87x53.34 mm). Shared on November 27th, 2014 08:19. NOTE: You probably shouldn’t order this board, it has known issues and will be unshared as soon as a replacement board is figured out This is a stripped down version of the full size laser cutter control board, using just enough parts to get the job done and nothing more. Two stepper drivers from Pololu needed, as is a handful of other parts, all available to read up on at Github: https://github.com/chimera/laser-cutter-control
