Board Dimension
Below shows the XLW‐002X wifi module dimension, the connector is male header connector with pin pitch of 2.0
mm. The XLW‐002X 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.
