A multifunctional module with an optical sensor for measuring the intensity of illumination, the color of the incident RGB light, the distance from the object and the detection of 3D gestures. Adafruit 3595

This BLDC motor controller, based on the Allegro A89301 chip, enables sensorless control over a wide voltage range from 5.5 V to 48 V and phase current up to 11 A without additional cooling. It supports four control modes: analog voltage, PWM signal, pulse frequency, and via an I²C interface with the ability to configure parameters and save settings to EEPROM. The Field-Oriented Control (FOC) algorithm ensures quiet and efficient operation, while built-in protection protects the system against short circuits, reverse polarity, and undervoltage.
