MCookie-Motor

Language:	English  • 中文

mCookie-Motor mCookie-Motor is a DC motor controller with PWM (Pulse Width Modulation) for various speed control. The speed of the motor can be controlled through PWM and direction (forward or backwards). This module needs to be powered with a sufficient power supply such as a BM shield with a BM module or with mBattery. Features Current & speed limited by internal PWM; Synchronous double-channel can reduce power consumption; DC motor braking mode; Capable of controlling two DC motors. Speed and direction control. Uses standard connectors: 2 pin, 1.25mm pitch JST connectors. Specification External power supply: BM module Pin Description mCookie pin Motor chip pin Function D6 1A Control 1A high level and rotate clockwise D8 1B Control 1B high level and rotate counter clockwise D5 2A Control 2A high level and rotate clockwise D7 2B Control 2A high level and rotate counter clockwise VMOT BM module Power supply GND GND Ground Note: The pins including 5, 6, 7 and 8 cannot be occupied by other sensors while using the Motor or it may cause problems. Module Motor must be powered on by mCookie-BM module, rather than by being connected to the computer through CoreUSB, otherwise it will result in that the application can't work.
