3.3.8 M.2 2230 Socket 1 Key E Connectivity Slot
It is possible to increase the connectivity of the SBC-C90
board by using M.2 Socket 1 Key E connectivity slot.
The connector used for the M.2 Connectivity slot is CN17,
which is a standard 75 pin M.2 Key E connector, type
LOTES p/n APCI0076-P001A, H=4.2mm, with the pinout
shown in the table on the left.
On the SBC-C90 board there is also a Threaded Spacer
which allows the placement of M.2 Socket 1 Key E connectivity modules in 2230 size.
Signal Description
/ USB_P5-: USB Port #5 differential pair;
P/PCIe0_Tx-: PCI Express lane #0, Transmitting Output Differential pair
P/PCIe0_Rx-: PCI Express lane #0, Receiving Input Differential pair
PC/ PCIe0_CLK-: PCI Express Reference Clock for lane #0, Differential Pair
PCIe_WAKE#: Board s Wake Input, it must be externally driven by the module inserted in
the slot when it requires waking up the system. Active low signal, electrical level +3.3V_RUN
with a 47K pull-up resistor
CLK_REQ0#: PCI-e Clock Request Input. Active low signal, electrical level +3.3V_RUN with
a 10
pull-up resistor. This signal shall be driven low by any module inserted in the
connectivity slot, in order to ensure that the SoC makes available the reference clock.
PCIE_RST#: Reset Signal that is sent from the SoC to all PCI-e devices available on the
M.2 Connectivity Slot (Socket 1 Key E type 2230) - CN17
