The 240 LEDs on the outer rings lend themselves to making a perfect analogue clock. Coupled with the 70 LEDs configured in two 5×7 blocks in the centre, you can add extra functionality like a temperature display, or even a scrolling message or stylised icons. The board also features an included ESP23-S2 running CircuitPython. You can add arcade buttons for extra functionality, and a diffused faceplate to smooth out all those LEDs. Check out the product page for a video demo of all those beautiful addressable RGB LEDs!
