Hello everyone,
I've just got hold of an old printer/scanner/copier I can't remember the make or model but it was a goldmine to dismantle! The power supply was even in a nice little double-isolated box, all ready to use
I'm having problems identifying the LCD character module I found, however. Marked "PC1602ARH-EWM-A-Y9Q" on a label, and "PB1602E-P7 (1.0)" on the board, I have figured out that it's manufactured by Powertip, it's a 16x2 module with no backlight, and it's possible that it was designed specifically for this application.
The closest match I can find is the Powertip PC1602E (Datasheet). The dimensions of the actual lcd component are exactly the same, but that one has has a 14 pin interface, and this has a 10 pin interface. Pins 1 and 2 are clearly gnd and +v, and from research I'm thinking that this could use a HD44780 compatible controller designed for 4 bit mode (From this Thread).
Attached is a photo. What do you think?
Thanks,
Barnaby
