Today we'll be taking a look on the Crystalfontz CFA632FNLY-U LCD screen from LC Design. This LCD screen is the 632 LCD screen from Crystal Fontz with a USB connection. It has 2 lines with a Yellow/Green LED Backlight and it's STN Negative, Blue. The USB connection makes the installation easier because you only need one cable for both power and data. The serial LCD modules need 2 cables, one for data and one for power. The USB version is fully compatible by using a 'Virtual COM port" driver.
