Mini-PCIe Connectors
The AcroPack Mini-PCIe connectors mate to TE Connectivity 1759457-1
connectors on the carrier board. AcroPack locations A and B are labeled on
the board for easy identification.
Pin assignments for these connectors are based on the Mini-PCIe specification
with the exceptions noted in Table 3.
WARNING: When installing a commercial mini-PCIe module onto the
XMCAP2022 board be sure that pin 45 on the module's mini-PCIe connector
is not grounded or damage to the module may result.

Notes:
1.
The following mini-PCIe signals are not supported: USB_D+, USB_D-, WAKE#,
LED_WPAN#, LED_WLAN#, LED_WWAN#, W_DISABLE#, COEX1, COEX2, UIM_C4,
UIM_C8, UIM_VPP, UIM_RESET, UIM_CLK, UIM_DATA, UIM_PWR. The following
signals UIM_C4, UIM_C8, COEX2 and COEX1 are repurposed for JTAG.
2.
TDI is tied to TDO on modules that do not use JTAG.
3.
+5, +12, and -12 Volt power supplies and their control signal have been assigned
to pins that are reserved in the mini-PCIe specification. This power is switched
