USB controller for Nokia color LCD

THIS IS UNTESTED, NO LCD. SOLD 'AS-IS'.

Due to supply issues we can't source the LCD for this project. The USB backpack PCBs are sold 'as is' to keep them out of the landfill. You might be able to find a suitable LCD at SparkFun.

This is a simple USB controler for the inexpensive displays found in Nokia phones. Screen contrast and backlight brightness are adjustable from software. A small booster supplies 7volts for the backlight.

• Control inexpensive color LCDs over USB
