Radiated Testing: There are two 0201 package 15pF capacitors (CA1 and CA2) on the board which determines if the RF signal is routed to the on-board antennas, or the U.FL connector. Only one can be populated at any given time. By default, CA2 is populated, and the RF signal is routed to the on-board antennas. This configuration will be used to execute radiated testing.

TestingConducted Testing: When the 15pF capacitor is rotated and installed in the CA1 location, the RF signal is routed to the U.FL connector P1. This configuration will be used to execute conducted testing.
Supplying with 12V
By default, the R3 resistor is unpopulated. If the user wants to supply the board with 12V through the 12V pin, R3 should be mounted on the board.
