Tip:
To connect the two power domains again, solder in a 0Ω resistor on the footprint or a 100-mil header
on the header footprint at the edge of the board and place a jumper between
VREG
and
VCC
.
CAUTION
Removing the resistor while the kit is powered without an ammeter or jumper may cause the ATtiny416 to
be powered through its I/O pins. This may cause permanent damage to the device.

LED
There is one yellow LED available on the ATtiny416 Xplained Nano board that can be turned ON and OFF. The LED
can be activated by driving the connected I/O line to GND.

Mechanical Buttons
ATtiny416 Xplained Nano contains one mechanical button. This is a generic user configurable button and when a
button is pressed it will drive the I/O line to GND.
Info:
There is no pull-up resistor connected to the generic user button. Remember to enable the internal
pull-up in the ATtiny416 to use the button.
