The TB6600 is a rugged, single-axis stepper motor driver tailored for CNC machines, 3D printers, and automation systems. It supports bipolar stepper motors, featuring micro‑step and current settings via DIP switches, and offers stable, fault-resistant operation through opto-isolated inputs and a robust H-bridge design.
Features
Handles bipolar stepper motors (e.g., NEMA 17/23/34) with 3.3–24 V control signals
Supports configurable micro‑stepping: 1, 2 (A/B), 4, 8, 16, 32
Adjustable current settings from 0.5 A to 4 A via DIP switches
Opto-isolated pulse, direction, and enable inputs to prevent signal noise
Semi-enclosed case with aluminum heatsink for passive thermal management
Protections: over-temperature, over-current, short-circuit, and input reverse-polarity protection
Energy-saving “half-current” idle mode reduces heat when idle
