3A Brushed Motor Speed Controller – Mini Bidirectional Forward/Reverse ESC Module
Take precise control of your DIY electronics builds with this compact 3A Brushed Motor Speed Controller. Designed for makers, hobbyists, and electronics enthusiasts, this mini bidirectional ESC (Electronic Speed Controller) module delivers stable, high-accuracy motor drive performance in an ultra-compact footprint — perfect for small DC motors, toy car modifications, mini UAV components, and more.
Key Features
- 3A Continuous Current Output: Built on a premium FR-4 fiberglass circuit substrate with an optimized 3A circuit layout, this board handles steady continuous current under rated load without overheating — keeping your motors and electronics safe from overload.
- High-Precision Motor Control: Dual integrated SMD control ICs paired with high-accuracy SMD resistors deliver precise voltage and current adjustment with minimal signal interference, reducing operation errors and giving you finer control over motor speed and direction.
- Superior Heat & Corrosion Resistance: Flame-retardant epoxy FR-4 base material ensures excellent heat dissipation and anti-corrosion performance, maintaining stable function through extended continuous operation and prolonging the module's service life.
- Bidirectional Forward & Reverse Control: Supports both forward and reverse motor direction, making it ideal for robots, RC vehicles, automation projects, and any application requiring flexible motor direction switching.
- DIY-Friendly Soldering Design: Pre-tinned copper soldering pads with clearly labeled polarity markings allow direct soldering without additional wiring harnesses — reducing assembly difficulty, saving installation time, and eliminating the risk of incorrect connections.
- Ultra-Compact Mini Form Factor: The miniaturized integrated circuit design takes up minimal installation space, making it a perfect fit for space-constrained builds and small electronic modification projects.
