Note 1: The xPico Wi-Fi SPI interface supports master only. Slave mode operation will be supported in a future firmware release.
Note 2: The xPico Wi-Fi USB interface is USB 2.0 full speed device. The device interface connector and power interface must be designed into the
mating board.
Note 3: xPico and xPico Wi-Fi embedded device servers may be designed into the same socket. Signals listed as no connect on xPico Wi-Fi
embedded device server may be connected on an xPico base design board. For example, xPico Wi-Fi pins 11, 12, 13, 17, 18, and 19 may connect
to an Ethernet magnetic module as designed for xPico (wired), however, Ethernet will not be available on those pins for xPico Wi-Fi.
Note 4: Pin 14 is the Ethernet duplex LED output on xPico (wired) and the system wakeup input on xPico Wi-Fi. For board designs supporting both
xPico (wired) and xPico Wi-Fi, a zero ohm resistor or removable jumper stuff option should be used to disconnect any on-board logic driving pin 14
when xPico (wired) unit is installed.
Note 5: The CP pins can be configured as pull-up or pull-down. The WKUP pin is not configurable and is always pull-down.
Note 6: The IO pins on xPico Wi-Fi embedded device server are configured as floating-input on reset until configured by firmware. For applications
requiring a high signal on power up, an external pull-up may be required or removeable jumper.
Note 7: It is highly recommended to connect RTS and CTS for serial port 1.
Note:
For integration information for Lantronix xPico Wi-Fi SMT embedded
device server modules, XPC W1002 and XPC W1003 please reference the 900-
714 xPico Wi-Fi SMT Integration Guide.
Mating Connector
The mating connector for the xPico and xPico Wi-Fi module is Hirose part number
DF40C (2.0)-40DS-0.4V (51). Special care must be taken when mating and unmating
the module to the mating connector. Refer to the Hirose DF40 data sheet below for
proper connector mating and unmating, along with the proper connector footprint.
Mating connector data sheet:
Antenna Interface (xPico Wi-Fi Units Only)
The xPico Wi-Fi module has been certified using the external antennas listed below. Per
FCC guidelines, the xPico Wi-Fi certification remains valid if using an antenna of similar
type to the antennas below. If using an antenna of similar type to one of the antennas
below, but from a different manufacturer part number the antenna gain must be equal to
or less than specified in the table. Consult with your certification lab for more details.
