This TB6600 chip-based driver is a bipolar type stepper motor driver module that allows for various micro-step modes. Compatible with 2 and 4 phase motors from 9V to 40V voltage, the maximum excitation current  4 A. Widely used in engraving machines, CNC machines, packaging machinery and other equipment. NEMA17, NEMA23, NEMA24 and NEMA34 motors work seamlessly with this controller. It is compatible with Arduino and other microcontrollers that can provide 5V digital pulse signal. The TB6600 stepper motor controller with wide-range 9~40VDC power. It is capable of producing a peak current of 4A, which is sufficient for most stepper motors.

Features Selectable mode of micro pitch (1/1, 1/2, 1/4, 1/8, 1/16 step). Current control (in 8 steps from 0.2 A to 5 A). Power Supply: 9~40V DC Optically isolated inputs Protection against over voltage, low voltage, overcurrent and short circuits. High starting speed. High-speed torque. Sturdy black plastic housing and black aluminum heat sink. Mounting holes above the heat sink for mounting the unit on machine panels.
