I was looking for something similar a while ago but didn't find it readily= =20 available. Instead I ended up having male headers on both the top and botto= m=20 board and soldered 2 female sockets (about 0.25" high each) together back t= o=20 back. Before soldering I bent the pins on the female sockets in opposite=20 directions so the male headers were still aligned straight on top of each=20 other. The two boards were about 20mm (0.8") apart. Not very pretty but it got the job done for this low volume home project. Otherwise Samtec has something they call Board Stacking Interconnect system= s=20 but that seems to be long male headers instead. Another option could perhaps be to use 2 IDC headers and a ribbon cable. /Ruben > Hmm...
