The Led Breadcrumb

red

Introducing the Led Breadcrumb (Led8Bus).

Are you fed up of fitting LEDs and current-limiting resistors time after time into your breadboard? It's surprising how often you have to do it, and how much room they take up. Well, this tiny little module is the answer.

At about the same size as a 16 pin DIP IC, this module has 8 individual surface mount (0805) LEDs along with 470Ω current limiting resistors (that's for 5V operation) and a common cathode connection

 Features

  • The size of a DIP16 chip - just half a square inch
  • 8 LEDs in various combinations:
  • All red
  • All yellow
  • All green
  • All blue
  • Bargraph - 4 green, 2 yellow and 2 red
  • Striped - Red, yellow, green and blue twice over.
  • Integrated current limiting resistors for use on most common logic voltages (aimed at 5V - will work at 3.3v)

 

I have several of these boards and they really are great to use on breadboards!.

Hi Mike, no connection to me or company. Was something I came across on eBay.

The LED breadcrumb looks really handy and the price is reasonable.

They have a Hex port reader that looks good to but can't find a link today.

The HEX display is undergoing a re-vamp at the moment and is not currently available. When it's done it will be 1,000,000% better in that it will be a PIC16 based module which is reprogrammable by someone with a suitable programmer (pickit3).

I like the new one even better Led8HEXv2. But you know what would be even better use the 8 led module you make and let it out put binary LED8BINv1 would be great to.

And then you maybe could toggle the button to set low to high catch or single port catch
be like a little logic tool.

That looks very nice, but, why only two digits?

Space and size. And 2 digits, in hexadecimal, is 8 bits. You want more digits, get more modules.

It really has some good uses I never tried the HEX idea out but have used 8 leds to catch a ports out put and save it.

Your site keeps lousing pages you get the 401 alot.

I'm in the process of moving servers at the moment, and am having to do funky things with VPNs and routing to move IP addresses around. It should settle down eventually.
