Using this 70 - pin receptacle header is easy. Just connect it to the Intel Edison Compute Module. This will let you add breakout boards more conveniently. When you're using it, be aware that it's a bit fragile due to its fine pitch. If it's not soldered down, it can be really hard to remove later, so take your time during installation. Also, remember that it's only rated for 30 connection cycles. When you need to disconnect it, pull it straight perpendicular to the connector plane. This will help you avoid bending or damaging the connector. After adding it to your Edison board, it will add 3mm of height to the socket. You can take advantage of this extra space by clearing the Edison's metal can and fitting some thin components or chips underneath for a more compact PCB. Keep these things in mind, and you'll get the most out of this connector.
