PCB is designed to represent a traditional U.S. flag, 300 mm × 180 mm, with four main LED sections:

​

1. Stars (Blue Field)

• 50 white LEDs arranged in the official alternating pattern

• Consists of 9 parallel branches:

  • 5 branches of 6 LEDs in series, with one 510 Ω resistor each

  • 4 branches of 5 LEDs in series, with one 510 Ω resistor each

​​

2. Blue LED Outline (Bottom and Right of Stars)

• 12 blue LEDs forming the border

• Consists of 2 parallel branches of 6 blue LEDs in series, each branch with one 510 Ω resistor

 

3. Top 7 Stripes (Right of the Stars)

• Represents the upper 7 stripes

• Consists of 10 parallel branches, each with 7 LEDs in series (4 red + 3 white, sequence R-W-R-W-R-W-R) and one 510 Ω resistor

 

4. Bottom 6 Stripes (Full Width)

• Completes the lower 6 stripes across the full board width

• Consists of 16 parallel branches, each with 6 LEDs in series (3 red + 3 white, sequence W-R-W-R-W-R) and one 510 Ω resistor​​
