Board Dimension
Below shows the XLW-210x wifi module dimension, the connector is male header connector
with pin pitch of 2.0 mm. The XLW-210x wifi module have an integrated PCB antenna which
requires the host PCB to maintain that area keep-out for best antenna peformance. Also, when
mounting on the host PCB of user's system, the module's PCB antenna should be on the edge of
host PCB and faced outward.
Connectors and Pin Assignment
Below shows pin define of XLW-210x wifi module. The pin 4 to pin 5 is usually used for Uart to
WiFi transfer, and pin 1、2 to pin 7 is usually used for GPIO.

This equipment generates uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced radio/TV technician for help.
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance 20cm
between the radiator & your body.
