The BIGAVR6 development system is provided with the MCP1541 circuit which generates voltage reference used for A/D conversion.
The microcontroller is supplied with such voltage, the value of which is 4.096V, through the AREF pin. In addition, the AREF pin can
also be supplied with the 5V power supply voltage. The position of jumper J18 determines which of these voltages is to be supplied
on the AREF pin.

The CN25 USB connector enables AVR microcontrollers with a built-in USB interface to be connected to peripheral devices. The
microcontroller is connected to the CN25 USB connector via USB-DM and USB-DP lines. The function of the LED diode marked as
ON is to indicate connection between USB devices
