LED32-DB37

Features

• 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 - let us know what value you want

• 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.

Wiring

• Male and female connectors are flipped
• Female from front

• Male from front

Test Procedure

Setup

• LED32-DB37 - Unit Under Test (UUT)
• PiPicoMite02 Based Test Station
  • PiPicoMite02 Processor card
• (2) DB37RIBBON cards
• (2) of 2x10 cables to connect between DB37RIBBON cards and UUT
• LED32-1 marked on cable end goes near HDR1 marked on UUT

Card Test Procedure

• Power up Test Station/UUT
• Type

chdir "/lbcards/GPIO32"
load " GPIO32-01.bas"
run

• Should see the LEDs go around the UUT card
• Hit any key to stop (after finishing rotation)
