Mikroe Brushless 21 Click

Mikroe Brushless 21 Click is suitable for controlling brushless DC (BLDC) motors with any MCU. The board features the Allegro Microsystems AMT49400 advanced 3-phase, sensorless BLDC motor driver with integrated power MOSFETs. The AMT49400 is rated for an operating voltage range from 4V to 16V. Motor rotation speed is controlled by applying a duty cycle command to the PWM input. An I2C interface is provided for setting motor-rated voltage, rated current, rated speed, resistance, and startup profiles. It features additional diagnostic circuits and drive-control functions like motor lock detection and over-current (short) protection.
