This chip called IS31FL3731 drives the LED lights - all 144 of them!

Later, when you turn on your Jay-D and start remixing, you'll also be able to change the LED animations that are controlled by this chip.

Nuvoton N76E616 is a real star here. This chip controls all the inputs coming from the encoders, sliders, and the rest of the buttons. It is also directly connected to the ESP-WROOM-32 microcontroller that turns all the inputs into fun outputs that bring Jay-D to life.

Chip CP2014 is important because it enables you to connect to the computer. It's also used as a USB-TTL converter.

Thanks to this little guy, the chip CP2014 can run without resetting each time Jay-D's connected to the computer.

This chip is Jay-D's sound amplifier. It's located right next to the ESP-WROOM-32 microcontroller and speaker connectors on top of the board.

There are two voltage regulators right above the chips IS31FL3731 and CP2014.

These small components are the main parts of pretty much every electronic device in the world. They are used to control the flow of the current in a circle.

There are a few locations on the board where these components are located, mainly around the ESP-WROOM-32 module and the display.
