WARP daughtercards use two 80 pin headers per daughtercard slot. The connectors are 0.5mm pitch, 4mm height headers with metal fittings from the Hirose DF17 series of connectors. The Hirose part number is DF17(4.0)-80DP-0.5V(57). See the Hirose DF17 Connectors Datasheet for the full mechanical details (pg 6) and recommended PCB footprint (pg 8).

The parts are available from Digikey; search for Digikey part number H11148CT-ND.
