Features: Double Motor Control: Features original TB6612 chip for precise control, supporting simultaneous driving of 2 or 4 encoding equipped DC6-15V motors with smooth speed regulation and minimal dead zone.. Wide Voltages Compatibility: Works with 6V 15V power input, compatibles 7.4V/12V lithium batteries. Integrated short circuit and over temperature protections ensures stable operating with clearly power indicators. Robust Power Output: Provides 5V (3A sustained, 5A ) and 3.3V (500mA) outputs to power controllers/sensors directly, simplifying wiring systems. Encoding Interfaces Ready: Includes pre corded phase encoding ports for closed loop speed control, enhancing precise in competitions or robot chassis builds. Compact Stackable Design: Space saving structure allows vertical mounting with STM32F407/MSPM0 boards, optimized for tight spaces in smart vehicles and electronic prototypes.
