32 LEDs
95mm wide (ODAS width) - 55mm depth matches other ODAS cards ODAS-PSOC5 (Rev X3 or higher), DIGIO32-I2C, etc
DB-37 male connector
(5) Ground pins (common ground)
3mm LEDs
6-32 mounting holes

Series Resistor Values
Pick a series resistor value assuming the LED forward voltage is about 2V.
Operating with 3.3V will require a smaller resistance than operating at 5V for the same current.
Standard series resistor values we carry are: 120, 150, 200, 220, 240, 270, 330, 470, 560, and 1K.
For 5V operation and not too bright LED (comfortable value for front panels) we use 560 ohms.
With 3V across 560 ohms that's only 5 mA (for 560 ohm resistor). For something with a lot of LEDs if they are too bright it can get annoying.
