12.1 RF Trace Layout Design Instructions
. The host PCB can follow these trace design to maintain compliance
under the modular grant (FCC) and Canada certificate (IC). Schematics, Bill of Materials (BoM), layout source files
and gerber files are available for download from the
SAMR30M Sensor board product page
.
The following is a snapshot of the schematic diagram for the host SAMR30M Sensor board showing the PCB
Antenna section.
