It offers two LED outputs with logic level conversion, a built-in I2S microphone, STEMMA QT port, button, NeoPixel and additional GPIO pins. With support for multiple platforms (Arduino, MicroPython, CircuitPython, ESP-IDF), it is ideal for wearable devices and interactive projects. Adafruit 6160

The Spectrum Shield enables your Arduino with the capability of splitting a stereo audio input into 7-bands per channel. You can then read the amplitude of each channel using the ADC on your Arduino allowing you to control everything from LEDs to motors, pumps to relays, or even fire, all with sound. DEV-13116

DC-AC converter, also referred to as an inverter. Converts a constant voltage (DC) of 12 V to an alternating voltage (AC) of 220 V

USB-CAN adapter with support for CAN2.0A and CAN2.0B standards. It can work with Windows and Linux systems, including Raspberry Pi and Jetson Nano minicomputers. Waveshare USB-CAN-A

This Kit with fully-dedicated PWM driver chip handles all the motor and speed controls over I2C. Only two data pins (SDA & SCL in addition to the power pins GND & 5V) are required to drive the multiple motors; you can also connect any other I2C devices or shields to the same pins. This  makes it drop-in compatible with any Arduino, such as the Uno, Due, Leonardo and Mega R3. Adafruit 1438
