Description
Mr. Spaghetti designed a rather unique light-up badge… let’s just say he didn’t wire the LEDs in the most optimal way. This badge features a 120x24 WS2812B LED matrix that displays a flag. The microcontroller controlling the LED matrix is a WCH CH32V003F4U6.
The PCB fabrication data for this badge and its firmware are available. Will you be able to figure out this flag?
Note: The order of the copper layers follows the standard convention, i.e., F.Cu, In1.Cu, In2.Cu, In3.Cu, In4.Cu puis B.Cu.
The silkscreen Gerber file is not provided; it is up to you to determine the placement and orientation of the components.
