Complete Wireless Control in a Micro Form Factor
When building custom electronics, space and power are your most valuable resources. This 433MHz Mini Motor Remote Control Module solves both problems instantly. Measuring just 21 x 11 x 5 mm, it is engineered to fit seamlessly into the tightest enclosures without compromising on signal strength or reliability.
Silent Operation with MOS Contactless Technology
Unlike traditional mechanical relays that produce an audible "click," this module utilizes advanced MOS contactless technology. This ensures completely silent operation—a critical feature for stealthy electronic locks, quiet robotic parts, or discreet automated mechanisms.
Engineered for Maximum Battery Life
Battery drain is a common headache for DIY hobbyists and engineers. We've optimized this receiver to draw an ultra-low standby current of just 0.5mA. When not in active use, it automatically enters a low-power sleep state, preserving your battery life for months rather than days. It fully supports a wide voltage range (DC 3V-12V), making it universally compatible with everything from standard 3.7V lipo batteries to 12V power adapters.
Built-In Smart Overcurrent Protection
Protect your hardware from unexpected surges. The receiver features integrated overcurrent protection. If your motor stalls or attempts to draw more than the rated limit, the module automatically cuts power, preventing damage to both the receiver board and your motor coil.

FAQ Section
FAQ Section
Q. Can I use this with a standard 12V power adapter?
A. Yes, absolutely. While it is highly optimized for battery-powered setups, it works perfectly with any stable DC power adapter outputting up to 12V. Just ensure your motor's current draw remains under the 0.4A limit.
Q. What happens if my motor gets stuck and draws too much power?
A. The module has built-in overcurrent protection. If the motor stalls and the current spikes beyond the rated limit, the receiver will instantly flash and cut power to protect your circuitry.
Q. How do I wake the module from sleep mode?
A. Because the module enters a 0.5mA low-power sleep state to save battery, simply press and hold any button on the remote for about 0.5 seconds to wake it up and transmit the signal.
