Epson 20×2 LCD

While digging through my pile of hardware I found a LCD display made by Epson. I’ve salvaged it from somewhere ages ago and decided to see if it works. After a little bit of google fun I found enough info about it in order to get it running with my Arduino. The display is Epson EA-D20025AR and it is Hitachi HD44780 compatible, but there’s a catch. The connector is only 14 pins and it’s wired differently than you would first think. The small marker on that 14-pin connector that usually marks pin 1 is used to mark pin 2 in this case. I found out that there has been lots of questions about this particular display, so look no further – here’s the pinout for it:
