Serial CPU Board
Mezzanine Connectors
Three connectors are available for SC4-CONCERTO 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.
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:
