Stackable femal headers with 15mm extra long square pins

Just got these stackable femal headers with 15mm in length and square cross section pins. It even provides enough clearance with RJ45 port underneath. The cross section is square providing good mechanical strength and good electrical clearance.

search on ebay with mjkzz to find it.

Just comment,
i used that type of female headers almost year ago on my Arduino shields http://pcb.daince.net, and my customer are very satisfied.

Please be aware , for ICSP connection you will need some modification to work correctly.
