6.13 PCIexpress (J25, J26, J27, U31 and Status LEDs)
PCIexpress lane0 from the COMexpress module is used to connect a 5-lane PCIexpress Gen1 switch
PEX8505AA. The Type 1 connection of the nanoETXexpress Evaluation Board offers a maximum of 5 PCIe
lanes from the module (PCIe0 ... PCIE4). The switch provides 4 additional PCIexpress lanes (PCIe5 …
PCIe8). See the detailed PCIexpress configuration in the list below.
J25 (PCIexpress x4 Slot) and J26 (PCIexpress x1 Slot0) are mechanical x16 slots to connect x16
PCIexpress cards. The electrical configuration does not match the mechanical:

6.14 PCI (J38, J39, U38)
According to the COMexpress specification PCI usually is provided by connector C/D. On the
nanoETXexpress Evaluation Board with Type1 connection PCI must be generated with a PCIexpress to PCI
Bridge.
The PCIe-toPCI Bridge PEX8112AA provides a maximum of 4 PCI Slots. PCI Slot0 (J38) and PCI Slot1
(J39) can be used on the nanoETXexpress Evaluation Board.
Note1: If PCIexpress and PCI can be used depends on the modules specification. Please refer to the module
documentation for further details. Appendix A gives a short overview.
Note2: The PCI IO voltage is set to 3,3V and therefore PCI is not compatible to 5V only cards.

6.15 Express Card (J41, J49)
The onboard Express Card is connected to PCIexpress Lane #6 (lane #2 of PCIe Switch) and to USB Port6.
To use the Express Card USB functions an ETXexpress module with at least 8 USB Ports is necessary.
Connector J41 allows using both ExpressCard/34 and ExpressCard/54. The maximum continuous Card
Power is
1,3A on 3,3V

6.16 SDIO & GPIO (J43, J48)
COMexpress defines a maximum of 4GPIs and 4 GPOs. With the new nanoETXexpress standard the 8
General Purpose Input/Output signals alternatively can be configured as SDIO interface. Refer to the
module's manual if SD Card feature is supported and how to be configured.
A TI74LVCH244A octal buffer provides galvanic isolation between SDIO and GPIO output connectors. J43
is active, if a SD Card is connected (Pin10, Detect).

6.17 LPC-I/O Controller (J21, U53))
The nanoETXexpress Evaluation Baseboard is equipped with an external LPC I/O Controller Winbond
W83627HFJ to provide standard legacy connections like COM or LPT.
To avoid address conflicts if a Super I/O is present on the COMexpress Module it's possible to switch the
Baseboard's Super I/O Address with jumper J25.

6.19 Backup BIOS (U48, J46)
The nanoETXexpress Evaluation Baseboard provides a backup LPC Firmware Hub U48. The backup BIOS
must be activated with jumper J46.
The yellow marked components are for an optional SPI flash (U57). In case of using an SPI flash jumper
J52 must be closed to activate it. A open jumper J52 enables the LPC Firmware Hub U48.

9 Limitations
Hardware limitations on PCB rev. L111:
The octal buffer is not able to switch between SDIO and GPIO. SD Card interface is
only working with desoldered buffer and assembled R380. A manual switching via
jumper will be implemented in newer designs.
The optional SPI Flash U57/J52 is not supported.
