Brushless 3 Click Board
Couldn't load pickup availability
The Brushless 3 Click Board™ carries the DRV10983, a three-phase sensor-less motor driver with integrated power MOSFETs. When an external power supply is applied, you can drive a brushless DC motor through the PWM pin, AN pin or I2C interface.
It communicates with the target microcontroller over the I2C interface, with the additional functionality provided by the following pins on the mikroBUS line: PWM, AN, INT, RST.d.

DRV10983 Driver Features
The DRV10983 is a three-phase sensorless motor driver with integrated power MOSFETs, which can provide continuous drive current up to 2A.
The DRV10983 uses a proprietary sensorless control scheme to provide continuous sinusoidal drive, which significantly reduces the pure tone acoustics that typically occurs as a result of commutation.
The interface to the device is designed to be simple and flexible. The motor can be controlled directly through PWM, analog, or I2C inputs. Motor speed feedback is available through either the FG pin or I2C.
