This is a PCB design I made for the Solder YSWS! I used KiCad to design the schematic, PCB, and making the bitmaps for the silkscreen drawings. For this PCB specifically I made a Molang themed keychain with LEDs that light up when you press the button on the side. Additionally, there's a potentiometer on the back so you can adjust the brightness of the LEDS!
