These modules are clean pulls from equipment, they have been used.
They are in good shape but may have a smudge or two. I sell lots of
these modules on eBay and everybody loves them! They feature an
industry standard Optrex-Compatible 14-pin interface (uses the
Hitachi HD44780 driver chip) so they are easy to drop into almost any
Using these modules is easy and fun! They operate on 5-Volts DC
and and are very "battery-friendly" ;) They also have a built-in
Electro-Luminescent backlight (requires ~90-120 Volts AC [see note
below]) for smooth, even lighting (No "hot-spots" like you get with
LED backlights!) They are great for use in Robotics, MP3 Players, PC
Status Displays, or any other project that needs a spiffy display.
Here are some links to more information:

interested in these excellent articles:

which are chock-full of useful information, circuit examples, sample
code and other interesting stuff.

If you have a HandyBoard[tm], BotBoard[tm], or other similar microcontroller board,
you may be interested to know that these modules will work with them
as well, but you may have to make a simple adapter cable as some of
those boards use a 14-pin inline style connector instead (making the
adapter is simple though- just wire pin 1 to pin 1, pin 2 to pin 2,
etc. until all pins have been wired - see the articles mentioned above
for more details)
If you want to operate them from a regular PC parallel port...
you can! You will need to make a custom cable however to
hook it up and be prepared to write some simple software to send
data to the module. Here is a link to a site with more information
on doing this:
How to Hook Up an LCD Module to a PC Parallel Port.
What you will receive: We have a number of these modules and
they come in several minor variations but are all basically the same.
The module depicted in the photo is for illustration purposes only.
The actual modules you receive may be slightly different but
guaranteed to work as presented. The only notable difference between
the modules is that most of them have a 14-pin male-header for
connection, while the rest have a short "pig-tail" cable (approx. 8"
in length) terminating in a 14-pin female connector.
Unless you specify otherwise, you will get "dealer's choice".
However, if you really want one or the other, just remind us when
you send in your payment and we'll make sure that you get the ones
that you want.
These modules are guaranteed to work!
We test them all before we ship them but if by chance, you somehow
get a dud, just return it to us and we'll send you another one.
Note: Please be careful hooking up the backlight. Don't use
ordinary house-current for this. While it will work, it is not the
smartest idea because if you accidently get zapped, mains power can
supply enough current to make it hurt (or even kill you!) Be smart-
be safe, use a switching-type circuit that is designed for this purpose
instead- or at the very least, a large wattage resistor and an inline
