The 1803BK DC Motor Speed Controller (PWM) is a compact, adjustable driver switch designed for lowvoltage DC motors. This package includes five units. Each controller accepts DC input in the 1.8V to 12V range and provides PWMbased speed control up to 2A and 30W to the motor. Control is via a small potentiometer for speed adjustment and an integrated on/off switch for simple operation. Key benefits Precise speed control for small DC motors using PWM, enabling smooth changes in motor speed without changing wiring or supplies. Compact, easytointegrate module suitable for hobby projects, robotics, and DIY gear. Integrated on/off switch provides quick power control without additional hardware. Pack of five units offers convenient replacements or multiplemotor setups in a single . Simple wiring and operation: connect power, motor, and control via the single PCB module for fast prototyping. Key attributes Model: 1803BK Type: DC motor speed controller with PWM Control: Adjustable via a potentiometer; includes an on/off switch Input voltage range: 1.8 V to 12 V DC Output current: up to 2 A Output power: up to 30 W Package quantity: 5 pieces per package Construction: PCBbased PWM controller designed for lowvoltage motor applications Compatibility and use cases Suitable for small DC motors in robotics, educational kits, and DIY projects requiring variable speed control. Use case 1: Drive a small hobby robot motor, adjusting speed with the potentiometer while keeping a simple on/off control on the same module. Use case 2: Speed control for model vehicles, such as a miniature car or boat, powered by 1.8–12 V DC supplies. Use case 3: Gentlespeed adjustment for small fans or beltdriven mechanisms in compact automation projects. Performance and reliability PWMbased speed control allows smooth transitions between speeds, enabling responsive control for dynamic applications. Designed for lowvoltage DC motors with a conservative current rating suitable for hobbyist and lightduty use. What you get 5 x 1803BK DC Motor Speed Controller (PWM) with adjustable driver switch, ready for integration into your lowvoltage motor projects.
