Mezzanine Connectors
Up to four connectors are available for PC7-FESTIVAL mezzanine expansion. Two high speed
signal connectors (HSE1, HSE2) and in addition a legacy I/F connector (EXP) are populated on top
of the CPU board. From PCB Rev.3 off, there is an optional GBE mezzanine connector for use with
the P82-GBE low profile module.
EKF offers low profile mezzanine modules which fit into the 4HP envelope of the CPU carrier card,
with varying B2B clearance from 9.5mm to 10.8mm, and also side cards for additional 4HP
mounting pitch (8HP in total assembly, 18.7mm B2B). The female connector EXP is identically
populated on carrier and mezzanine and requires a suitable pin header (stacker) as contact
element between carrier and mezzanine in addition. The HSE1/HSE2 connectors of carrier and
mezzanine are female (CPU) and male (mezzanine) pairs, selected to match the individual B2B
height requirements:
