ATtiny1627 Curiosity Nano Pinout

All the ATtiny1627 I/O pins are accessible at the edge connectors on the board. The image below shows the board

pinout. For all available functions on each pin, refer to the I/O Multiplexing and Considerations section in the

ATtiny1627 data sheet.

Using Pin Headers

The edge connector footprint on ATtiny1627 Curiosity Nano has a staggered design where each hole is shifted 8 mil

(~0.2 mm) off-center. The hole shift allows the use of regular 100 mil pin headers on the board without soldering.

Once the pin headers are firmly in place, they can be used in normal applications like pin sockets and prototyping

boards without any issues.

Tip:  Start at one end of the pin header and gradually insert the header along the length of the board.

Once all the pins are in place, use a flat surface to push them in.

Tip:  For applications where the pin headers will be used permanently, it is still recommended to solder

them in place.
