The module is delivered in it's
original antistatic bag. |
 |
|
As can be seen, the protective sheet
on the display is still in place.
Before you ask, no, no backlight on this one...

A nice side view. I lifted the protection
plastics a little, that's why it looks as it does.
The four pushbuttons are high quality with
gold plated internal contacts.
Note that the unit is delivered
with an antistatic plastic protection on the 24-pin
connector. |

|
The back of the unit. Not much more then
the LCD controler and the 24-pin connector.
The PCB is a four layer PCB with grounds on both
outsides, which gives god screening and protection
against interference. |

A close-up after I've lifted the label from
the LCD controler. A plain standard Hitachi
HD44780 controler. Not even a "me-to", but
the original !
So it should work easily with the
large amounts of microcontroler code for the HD44780
out there on the net... |
 |
The 24-pin connector. High quality as the rest
of the unit, with gold plated pins. |
 |
|
And here we are going live !
This display was produced from a LCD test
program from the net, running completly
unmodified. Any code for the HD44780 controler
would probably work, I'd guess...
The cable is a bit messy, but worked on first try.
In this case, the display is running in 4-bit mode
with R/W hardwired to GND (write-only).
(The PIC processor board in
the background running the test program is not mine,
it can be found here. (Nice board anyway...)

Matching 24-way cable and connector for the module.
The cable is 8" (20 cm) in length.
With the connector mounted : $3.50 each.
With the connector un-mounted : $2.50 each.
The other end of the cable is left open, so one can
connect it as one like. |
