Adafruit 16-Channel 12-bit PWM/Servo Shield - I2C interface

Audio receiver with Bluetooth 5.0 communication based on the QCC3008 module. It can be powered with the voltage from 3.6 V to 5.5 V, including with a lithium battery

This controller allows independent control of three DC motors using a single I²C bus. It supports motor supply voltages ranging from 4.5 to 44 V and currents up to 0.8 A continuous per channel, making it suitable for a wide range of robotic and mobile applications. I²C communication eliminates the need to generate PWM signals and significantly saves microcontroller pins. The ability to connect multiple controllers on a single bus allows for easy scaling of the system to larger motor counts. Pololu 5083
