TT-Duo Motor Control Module

Bring your 3D printed models to life with the TT-Duo Control Module; a compact, plug-and-play solution designed for kinetic creators. This powerful little board drives two TT motors with full independent control over speed and direction, all powered by a single USB-C connection.

At its core, the TT-Duo uses a dual-timer NE556 IC to generate precise PWM signals, tuned via RC oscillator circuits for reliable, analog control. These signals are amplified by the proven TB6612FNG dual H-bridge driver, delivering clean, efficient power to each motor without noise or lag.

No programming required — just pure, rock-solid linear electronics. Adjust speed with onboard potentiometers, flip direction with toggle switches, and start building right away.

While built for TT motors, the TT-Duo is versatile: use it to control small servos, custom LED animations, DC cooling fans, or any low-power PWM-driven device. Whether you're a hobbyist, educator, or 3D printing designer, the TT-Duo opens new doors for dynamic, interactive builds — no code, no complexity, just motion.
