Removed from very specialised broadcast equipment (deemed to be no longer useful in the industry)
Working perfectly - no faults
Great as a "drop in" replacement LCD screen or for a custom project based on Arduino for example
Tian-Ma Microelectronics LCD display
Model: TM402CD
Integral ST7066U LCD controller
5x7 matrix character generation
40 characters x 2 line
Character size: 3.2mm x 5.55mm
Polariser: transflective
Background colour: Yellow/Green
LED backlight
8 bit parallel data input
All inputs and outputs are available on a 16 pin male strip and for convenience, a short ribbon cable is supplied to suit
The function of each pin on this connector is clearly explained in the supplied datasheets
These can nominally run with up to 7V but, as in the case of the equipment this was removed from, a 5V supply is more "normal"
Module dimensions: 182mm x 33.5mm x 11.2mm (quite large)
Supplied with complete technical datasheet which gives the command codes, character generator codes etc
Supplied with the clear perspex window that is mounted in front of the LCD screen (for protection) and the mounting hardware for this window is also supplied
COSMETIC CONDITION:
Excellent
No damage at all to the module or the window
No segment/LCD damage
TESTING:
Immediately prior to removal from the specialised broadcast equipment, I checked once again and also have taken a photograph of the LCD active before the equipment was dismantled
No issues at all
The equipment this LCD display was removed from did not have a fault, it was simply obsolete!
Since removal, this module has been stored in an ESD bag and will be supplied in this manner (with the datasheets if required - 30 pages!)
