The SP4-MAMBO requires a single PCI Express® lane from
the backplane, passed over across the connector P1 to a
PCIe Gen2 packet switch (upstream port). The PCIe
downstream ports from the switch are used to supply
each Mini Card socket with an individual PCI Express® link,
as required e.g. by WLAN Mini Cards. Another port from the
PCIe packet switch feeds an on-board USB 2.0 controller,
which is required for USB type Mini Cards, such as most modems.
The related SIM card holders are suitable for 15mm x 12mm
Micro SIM cards, which are most widely in use.

Any CompactPCI® Serial peripheral slot - in addition to its PCIe link -
may provide a SATA channel and also an USB port, available from the
backplane via connector P1. These ports are both routed to the optional
on-board mSATA socket (SSD storage module). The SATA Rx/Tx signals are
reconditioned by a 6Gbps SATA redriver, for optimum signal integrity.
The mSATA connector can be used also with an USB style Mini Card.
The associated Micro SIM card holder is positioned below the Mini Card
module itself, due to space restrictions on the SP4-MAMBO PCB.
