Using Pin Headers
The edge connector footprint on ATtiny1607 Curiosity Nano has a staggered design where each of the
holes is shifted 8 mil (~0.2 mm) off center. The hole shift allows the use of regular 100-mil pin headers on
the kit 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 all the way in.
