LCD Connector
The LCD Connector has 18 pins, but only 16 are required for simple LCD panels. If using an OPTREX 51505 or
equivalent, use pins 1-16, if using a LUMEX LCM-S02002DSR or equivalent, use pins 3-18.
Two potentiometers are provided for LCD control. R34 adjusts the backlight and R35 adjusts the contrast. Power for
the LCD panel is provided by the 3.3V to 5V converter at U7.
