I'm confused about the resistor values used on the user LEDs on the BBB. The first question is, the power LED (D1) is on a 3v3 circuit. The datasheet for that LED says the fwd voltage is around 3V @ 20mA. No matter how I spin it, i can't figure out how in the world they came up with an 820 ohm resistor?? (3.3 - 3.0) = (0.020)(R).. ?
The second question is, the USER LEDs (D2. D3. D4. D5) are on a 5V circuit. Yet guess what, they still somehow figured on an 820 ohm resistor??
