The PCB was developed to control any addressable RGB LED strip that uses WS2812B or similar LEDs that take 3 inputs (VCC, GND and Data/DIN) using any DIP8 packaged microcontroller. All board traces ...

The PCB layout if using a single LED array. When building this version I suggest fitting the LED bargraph last to make the board assembly easier. This board has one small link marked in red.
