RioRand makes speed controller
Check the specs before ordering. Don’t use beyond the range—could cause issues.
Got questions? Hit us up anytime.
We’ve seen too much inefficiency from unstable speed control and countless failures from mismatched specs. So a team of veteran motor control engineers built RioRand controllers. Every detail—AC/DC compatibility, brushed/brushless support, micro-current adjustment, high-load stability—gets tested hundreds of times.
We know the right fit matters. That’s why RioRand keeps specs transparent: clear voltage ranges, current limits, motor types.

RioRand Mini DC Motor PWM Speed Controller
This compact PWM speed controller is designed for DC motor speed regulation and LED brightness adjustment, with a wide operating voltage of DC 3V-35V (djustable 3V-15V low-voltage mode)and 5A rated current. It features a 10kHz stable PWM frequency, 1%-100% adjustable duty cycle(Precise speed & brightness control), and built-in self-recovery fuse for safety(Automatic reset after cooling). With a mini size of 30×24×15mm and 15g lightweight, it's easy to install and carry, ideal for DIY projects, home workshops, and LED dimming applications.
