The board you assembled is an RP2040 powered LED board. It contains three potentiometers that control the R, G, and B values of the LEDs and a button to adjust the brightness. You also received a wood and acrylic sign that can be used to to display the WPW 2025 logo. The neat thing about this project is that it's entirely customizable!
The board in your hands is essentially a mini Arduino running CircuitPython. You have access to 12 GPIO pins, 5V and GND. With this knowledge you can program the board to do whatever you want! Add a photoresistor to make the LEDs change brightness based on the ambient light. Add a screen to display the current time! There's a ton of different possibilities.
If you'd like to start programming the board, plug it into your computer! You'll notice that it opens up the file explorer and there should be a code.py in it. That's your main program. You can edit it in any text editor, but we recommend Mu Editor. It's a simple IDE that works well with MicroPython. You can download it here: Mu Editor.
This is a great board you can use to really explore fun Arduino style projects. If you would like to learn more, visit these links:

If you ever want to switch the acrylic and wood, you can laser engrave a new piece of acrylic and wood. They are both 100mm x 100mm and the acrylic is a reflected image from the wood.
