Lcd Display - FiveCo FMod-IPAXESCTRL User Manual

LCD Display

The FMod-IPAXESCTRL board drives an LCD
display with 20 columns and 4 lines. LED
backlight is also powered from the FMod-
IPAXESCTRL, and always ON.
Different LCD colors are available, FiveCo
recommend the LCD's from Crystalfontz
(www.crystalfontz.com)
The LCD used by FiveCo is the Crystalfontz
model CFAH2004A-TMI-JP (with LSI HD44780
driver inside), blue-backlit with white characters
(pictured on the left).
The connector on the FMod-IPAXESCTRL
board has the same pin configuration as the one
of the LCD (allowing an easy flat-cable
connection), but the LCD has to be used in
4bits data mode only.
