MC33886 Motor Driver Board
It is a high current motor driver board that adopts Mc33886 motor driver chip. The driver board can drive two motors at the same time, the output current can reach 5A, and motor PWM speed regulation can be realized. It has real-time control functions such as braking. It has over-current, low voltage and over-temperature automatic protection.
Technical Specifications
- Dimension: 46x48mm
- Operating voltage: 6.5V ~ 24V DC
- Internal resistance: 140 million ohm
- PWM frequency: <10KHZ
- Maximum current drive: 5A
- Temperature range: -40°C ~ 125°C
- Access control and motor running status (1 means high level, 0 means low level)
Matters needing attention
- When connecting, each pin has a corresponding logo and you can check it carefully. Do not reverse the positive and negative ends of the power supply.
- Do not exceed the maximum operating current and operating voltage of the driver while it is operating.
- Pay attention to the temperature of the mc33886 chip while the driver is operating. If the heat is too serious, please stop working.
- (FS1 FS2) error status indicator. Under normal conditions, output 0 is low. When the motor is commutated, the transient current of the loop is relatively large, exceeding the overcurrent protection threshold of the chip. When the FS continues to drop, please turn it off immediately to prevent it from burning.
