Tip:
For applications where the pin headers will be used permanently, it is still recommended
to solder them in place.
Important:
Once the pin headers are in place, they are hard to remove by hand. Use a set of
pliers and carefully remove the pin headers to avoid damage to the pin headers and printed
circuit board.

Peripherals
4.2.1
LED
There is one yellow user LED available on the ATtiny1607 Curiosity Nano kit that can be controlled by
either GPIO or PWM. The LED can be activated by driving the connected I/O line to GND.

4.2.2
Mechanical Switch
ATtiny1607 Curiosity Nano has one mechanical switch. This is a generic user configurable switch. When
the switch is pressed, it will drive the I/O line to ground (GND).
Tip:
There is no externally connected pull-up resistor on the switch. To use the switch, make
sure that an internal pull-up resistor is enabled on pin PC4.

On-Board Debugger Implementation
ATtiny1607 Curiosity Nano features an on-board debugger that can be used to program and debug the
ATtiny1607 using UPDI. The on-board debugger also includes a Virtual Com port interface over UART
and DGI GPIO. Atmel Studio/Microchip MPLAB
®
X can be used as a front-end for the on-board debugger
for programming and debugging.
can be used as a front-end for the CDC and DGI GPIO.

On-Board Debugger Connections
The table below shows the connections between the target and the debugger section. All connections
between the target and the debugger are tri-stated as long as the debugger is not actively using the
interface. Hence there is little contamination of the signals the pins can be configured to anything the user
wants.
For further information on how to use the capabilities of the on-board debugger, see Section
