Description

DC 1.8V‑35V PWM Motor Speed Controller – Adjustable 2A‑30A Drive Module

Take full control of your low‑voltage DC motors with our high‑performance PWM (Pulse Width Modulation) speed controller. Designed for hobbyists, makers, and industrial applications, this compact module delivers smooth, precise speed regulation from 1.8 V up to 35 V and supports continuous currents from 2 A to 30 A (30 W‑90 W). Whether you’re building a robot, a RC car, a CNC spindle, or a DIY power tool, this controller provides the reliability and flexibility you need.

Key Highlights

• Wide Voltage Range: Operates from 1.8 V to 35 V, perfect for 6 V, 12 V, 24 V, and 36 V battery packs.
• Adjustable Current Capacity: Choose from 2 A, 3 A, 5 A, 10 A, 30 A (30 W‑90 W) to match your motor’s power rating.
• Precise PWM Control: 0‑100 % duty cycle with 0.1 % resolution for ultra‑smooth acceleration and deceleration.
• Built‑in Protection: Over‑current, over‑temperature, and short‑circuit safeguards extend motor life.
• Compact & Easy to Mount: 30 mm × 20 mm PCB with screw‑hole layout for quick integration.
• Universal Compatibility: Works with brushed DC motors, stepper motors (single‑phase), and low‑voltage gear drives.

Why Choose This PWM Motor Speed Controller?

Our controller combines a rugged MOSFET power stage with an intuitive potentiometer (or external voltage) input, giving you real‑time speed adjustment without the need for complex programming. The low standby current (< 10 mA) helps conserve battery life, while the high efficiency (up to 95 %) minimizes heat generation.
