43oh

Green 7-segment LED modules


Recommended Posts

All of these display modules came from old computers that had turbo buttons (you know, push turbo, turn your 33mhz into a 66mhz).

 

$1.50 each, please specify which one(s). Buyer pays shipping/handling. Will take offers for trade.

Each module will come with the appropriate amount of jumpers to light all segments, arranged like the third photo:

If the one with the broken pin can be de-soldered, I will take it, for the asking price of the rest, but before I make a commitment, are they common anode or common cathode? Because I really need a common cathode display.

I'm afraid they are common anode, and they have only one common for all 21 segments. The pin spacing on the display itself is not the usual size for breadboards or ICs, it's smaller. The way this board is shaped, I can desolder the jumpers' ground pins, and then it will fit in a breadboard without any more major modifications, acting like a breakout.

 

Since you need a common cathode, I could include four desoldered HC04's for an extra $1.50.

 

I tried to post a pic of the display board pins, but all that happened was my browser said it was waiting for 43oh. Might be my connection again. Will try again later to add it to this post.

Left to right:

The square is a green led, the two terminals under it belong to it.

The first rectangle is two green leds, the four terminals under it belong to it.

The second rectangle is two red leds, the four terminals under it belong to it.

The third rectangle is two amber leds, the four terminals under it belong to it.

Now what did I do? :eh:

Where the hell is that module from?

It was the display in a socket in a VERY old cell phone. Sadly, there was only one in the vanful of parts from the attic of that computer store... :(

 

I wonder if there are any of those old cellphones on the bay of e? :think:
