PC1602K-P9 LCD pinout
« on: February 25, 2022, 02:34:04 pm »
Can any body help me with the pinout for this display please?
It is a "POWERTIP" PC1602K-P9 module (16x2 characters), based on a S6A0069 controller, which is similar to the HD44780.
It is from an old network switch

I traced out what I can, see attached schematic and photos.

Thank you for any assistance.

If you have the device it came from, and a scope or logic analyser, you can find out the remaining pins. It's probably being used in 4-bit mode judging by the number of pins left over on your schematic.

First I tried searching for "pc1602k-p9" then on images I found some photos from this page. Last post contains dead link to datasheet, but provides another parts number that shows what you look for.

Brilliant! I also initially tried to search for images, but only found this site: https://www.elektroda.pl/rtvforum/topic3408653.html

What search engine do you use?

Just for completeness, this display work 100% using the provided datasheet by kjr18:-+
It seems to be 100% compatible with the HD44780 and associated Arduino libraries.
Just take note, EN (pin9) and VO (pin15) must be connected to +5V.

I used Google. DuckDuckGo only shows this one thread on this one forum.
