Open-Q™ 820 Development Kit
Note that two dual-band (2.4GHz + 5GHz) antennas are required to be connected to achieve full performance
of the Wi-Fi interface. If only Bluetooth is being used, then only a single 2.4GHz antenna connected to ANT1
is necessary.
The SOM WiFi/BT module has received regulatory certifications (see FCC ID: 2AFDI-ITCNFA324 for details).
Please note that the on board PCB antennas were not the antennas used for the SOM WiFi/BT module
certification. Refer to the certification documents for the WiFi/ BT module (see R-4) for information regarding
the test configurations used for certification. Deviating from the documented configuration may trigger the
need for re-certification.
For details on connecting the WiFi module to the on board PCB antennas on the carrier board, refer to section
3.8.14 below.
WGR7640: GPS Front End WGR7640 is the primary GPS radio interface used on the Open-Q 820
