PW2050 Embedded Device Server Integration Guide 15
Note1: The current module supports 10/100Mbps Ethernet. Additional pins have been called out for a future Gigabit
Ethernet module.
Note2: The logic IO pins are 3.3V tolerant.
Note3: Pins 109 to 124 are the large ground pads under the module. These pads should be connected to ground.
These pads also provide thermal relief for the module. It is recommended that multiple vias for each pad be used to
connect the ground pads to the ground plane.

Pin Locations
Note: Pins 109 to 124 are the large pads under the module. Pins 109 to 124 should be
connected to GND. The pads in yellow are for future module revisions and should be left
unconnected.
Antenna Interface
The PW2050 Wi-Fi module has been certified using the external antennas listed below. Per
FCC guidelines, the PW2050 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. Refer to the PW2050 Wi-Fi SMT Embedded Device Server Data Sheet
for full compliance instructions and information. Consult with your certification lab for more
details.
