Help identify two LCD modules

Hello! New to posting but not new to reading the forums...

I seek help. I've got two LCD modules (don't know what/where they came from) that I cannot seem to identify. They are Crystalfontz modules, the name is clearly plastered on the boards. Anyone have any ideas? Perhaps instructions on how to use them? Thanks!

I would pass them up if I don't have a datasheet. Just my two cents, this may prove to waste you more time than it's worth.

Yesterday I probably only spent 20 minutes top hooking up a compatible 128*64 graphic LCD (solder and jumper wire) and loaded the demo and there it goes, enjoy!

BTW, how much did you pay?

I dont know why but I never thought of asking Crystalfontz.

They were free. My line of work I come across all kinds of electronics. I get oodles of LCD screens but most of them are 16x2, a few 20x4s. These little modules looked like they had a future, maybe not :frowning:

I'll ask CF see what they say. My guess is they came off some networking gear. I have a couple other similar modules that were from some F5 networking equipment.

They said they cannot release any information on the modules. Contract, copyright stuff. oh well :-/
