XT1 Jumper
RESET Jumper
The STK520 includes a potentiometer. To use the potentiometer, please mount JP13
and JP14 jumper.
The potentiometer is supplied by AREF and it delivers a voltage to the AVR ADC0 input.

As the jumper JP1 (XT1) is short circuited by Printed Circuit Board wire, it’s always ON.
So it’s not mounted. To open this jumper, it’s necessary to cut the wire between JP1 pin
(solder side).
It’s possible to open XTAL1 circuit which comes from STK500 board by removing the
XTAL1 jumper on the STK500 board.
As the jumper JP3 (RESET) is short circuited by Printed Circuit Board wire, it’s always
ON. So it’s not mounted. To open this jumper, it’s necessary to cut the wire between
JP3 pin (solder side).
It’s possible to open RESET circuit which comes from STK500 board by removing the
RESET jumper on the STK500 board.
