I bought two JeeNode 915 kits V5 and for the qty 4 6 pin female I/O headers they had
right angle connectors. They should be straight. (both kits)
Any reason why?
Right-angle headers (especially female) are easily straightened out with pliers - and give users the possibility of either orientation. Jean-Claude Wippler of JeeLabs is more inclined to solder straight headers on surface-mount style at right angles. We think having more mechanically robust headers are a good idea.
In either case, if you don't already have a good pair of needle-nose or thin-nose pliers, you could use one.
