These boards simply provide 8 LEDs connected to 8 pins (a flying lead provides ground).

  • 8 LEDs
  • less than one inch long
  • only 8 i/o pins used
  • Use for port diagnostics
  • get one board of each colour!
  • 0.7" by 0.9" (18mm by 23mm)

Circuits dont get a great deal simpler than this!

Each pin controls a single LED. When the pin is set to output a 'high', the LED will light.

The on-board current-limiting-resistors are suitable for 5v supplies, but all except the white model will work at reduced-brightness on 3v (The white LEDs need more than 3v to light).

Sample code that demonstrates all 8 LEDs is available from the link below or on the downloads page.

These boards are available with either straight header pins (as shown in the picture), or with right-angled header pins. Right-angled header pins mean that the board will stick up vertically from your breadboard. It saves a small amount of breadboard space at the expense of mechanical stability.

The following versions are available;

version voltage comments
Red 5v/3v slightly dimmer at 3v
Yellow 5v/3v slightly dimmer at 3v
Green 5v/3v slightly dimmer at 3v
White 5v will not work at 3v
