4.1.2 Using Pin Headers

The edge connector footprint on AVR128DA48 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.

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 PCB.
