C.2 Contrast Adjustments for All Boards
Depending on when you acquired your LCD/keypad module, you will be able to set the
contrast on the LCD display by adjusting the potentiometer at R2 or by setting the voltage
for 5 V by not using the jumper across any pins on header J5 as shown in Figure C-2. Only
one of these two options is available on a given LCD/keypad module.
User’s Manual
NOTE: Older LCD/keypad modules that do not have a header at J5 or a contrast adjust-
ment potentiometer at R2 are limited to operate only at 5 V, and will work with the
Prototyping Board. The older LCD/keypad modules are no longer being sold.
