Bill of Materials

• 5mm color changing LED (quantity 1):

  • EDGELEC 100pcs 5mm RGB Slow Flashing LED Diodes Multicolor

• Resistor (quantity 1):

  • E-Projects 500EP5141K00 1k Ohm Resistors
  • E-Projects 500EP514470R 470 Ohm Resistors
  • NOTE: Resistor value should be chosen based on personal preference for brightness. I found the LED to be too bright with 470 Ohm while inside my apartment with indoor lighting. I preferred to make the LED dimmer with 1K Ohm.

• 4 pin connector for the Badge (quantity 1)

  • Digi-Key Part Number: S7105-ND
  • Manufacturer Part Number: PPPC022LFBN-RC
  • Description: CONN HEADER FMAL 4PS .1" DL GOLD

• 2 pin headers for the Add-on board (quantity 2)

  • Digi-Key Part Number: 952-2261-ND
  • Manufacturer Part Number: M20-9990245
  • Description: SIL VERTICAL PC TAIL PIN HEADER
  • NOTE: it is much cheaper to buy 2 pin headers, use two of these 2 pin headers per Add-on board to yield a 4 pin header.
