ADJC Potentiometer

There is a ADJC potentiometer, which allows to control the contrast on LCD. Then output pin ADJC
must be connected with LCD`s pin CONT.

ADJREF Potentiometer

Allow to adjust reference voltage of ADC in range from 0V to VTG. It is connected by jumper AREF to

one of microcontroller’s por

t.

3V3POT Potentiometer

The board is equipped with one potentiometer, allowing to regulate voltage VTG between 3.3

–

1,25V

(even if 3V3 jumper is closed).

RESET Switch

Allow to apply external reset.
