Motor controller, H-bridge speed regulator, 1 piece, DC5-12V industrial supplies for Arduino smart car current limit DC controller

Features: 1. The improved product comes with a heat sink to enhance reliability and a current sensing circuit to achieve a perfect closed-loop PID design. 2. This board features a high-speed switch. General coreless motors require a PWM frequency of 60 kHz, and this board is designed with a 200 kHz switch. 3. Suitable for all types of toy car motors, solid-state refrigeration control, DC motors, and electromagnetic deflection coil control. 4. This board can withstand high current overload and has a braking function that can stop the motor quickly. 5. The input voltage range of this board's single power supply is 3 to 15V. If you are using a power supply below 12V, this board is very useful. It can still operate even if the voltage of a 12V battery drops as low as 3V. Specifications: Description: This driver board is specially designed for coreless motors and will work perfectly with them. It supports forward and reverse motor control and PWM speed control. This board uses a MOSFET with extremely low internal resistance and deadband control, minimizing MOSFET switch losses and improving power utilization. The MOSFET driver chip has integrated hardware braking and energy feedback functions. It is a good choice for ordinary DC motors and coreless motors, etc. Features: The upgraded product comes with a heatsink to improve reliability and a current sensing circuit to achieve a perfect closed-loop PID design. This board features a high-speed switch. General coreless motors require a PWM frequency of 60 kHz, and this board is designed with a 200 kHz switch. Suitable for all kinds of toy car motors, solid-state refrigeration control, DC motors, and electromagnetic deflection coil control. This board can withstand high current overload and has a braking function that can stop the motor quickly. The input voltage range of a single power supply for this board is 3 to 15V. Even when using a power supply below 12V, this board is very useful. It can still function even if the voltage of a 12V battery drops as low as 3V. The MOSFET can withstand a current surge with a resistance of 0.003 ohms, which allows for rapid opening of the MOSFET channel, improving the motor's acceleration curve, and also enabling rapid motor braking. This allows the car to start and stop quickly.
