The TB6600 Stepper Motor Driver is a powerful, industrial-grade driver for controlling NEMA 17, 23, and 34 stepper motors in CNC, 3D printers, and robotic systems. With wide voltage input (9–42V), 4A output current, microstepping support up to 1/64, and automatic current downshift, this driver is ideal for high-performance, smooth motion control using Arduino, Raspberry Pi, or other controller boards.
The UNI‑T UT 33+ Series are compact, rugged, True RMS digital multimeters built for everyday use. Housed in a shock‑resistant body that survives 2 m drops, they offer 2000‑count resolution, 600 V voltage, 10 A current, continuity test, diode check, and specific features per model: capacitance (A+), battery test (B+), temperature (C+), and NCV (D+)
