RioRand PWM DC Motor Speed Controller – 6V-28V 3A Reversible Speed Regulator with Forward/Reverse Switch for Low Voltage Brushed DC Gear Motors, Hobby & Small Automation Projects

Smooth PWM Speed Control & Wide Compatibility：This DC motor speed controller utilizes Pulse-Width-Modulated (PWM) technology for stepless speed adjustment. It supports DC 6V-28V input, a maximum continuous output current of 3A (do not exceed 3A), and up to 80W output power, compatible with most low-voltage brushed DC gear motors for hobby and small automation use.
Forward/Reverse Direction Control：A 3-position toggle switch enables easy switching between forward, stop, and reverse modes for your DC motor. The 15cm/5.9in switch cable is made of ultra-soft, high-temperature resistant silicone wire, supporting flexible installation and long-term durability.
Critical Safety & Usage Restrictions：Designed exclusively for DC power sources: never connect to 110V/220V AC household power, and do not reverse positive/negative power connections (both actions will cause permanent damage). This controller is for low-voltage brushed DC motors only, with a maximum load current of 3A—avoid use with high-current motors (e.g., 775 motors).
Suitable for Hobby & Small DIY Projects：Suitable for hobby & small DIY projects popular among U.S. makers: small robotic builds, RC vehicles, model trains, small cooling fans, and student electronics experiments. It provides reliable PWM speed control and reversible direction for low-power DC motor setups.
Compact Design & Package Details：Measuring 3.2×5×1.5 cm (1.3×2×0.4 in) and weighing ~1.13 oz, this lightweight controller fits easily into small enclosures. Package includes 1 x RioRand DC Motor Speed Controller. Note: This is a speed controller, not a voltage regulator—verify compatibility with your motor and power supply before purchasing.
