TB6600

A high-current stepper driver for machines that actually do work: CNC routers, larger 3D printers and automation axes. Optical isolation between the control side and the motor side keeps switching noise out of your Arduino, which is the difference between a machine that runs all day and one that loses steps randomly. DIP switches set current and microstepping, so no soldering or code changes are needed to retune it. Set the current to match your motor's rating before first use, and fit it where air can reach the heatsink. Opto-isolated inputs keep motor noise off the controller; DIP switch setup for current and microstepping, no code needed; Handles NEMA 17 and NEMA 23 motors comfortably; Aluminium housing acts as the heatsink
