3.1.2 Antenna and U.FL Selector

The board can be configured to route the RF output from the CC256xC to the onboard copper antenna or the onboard U.FL connector. This configuration is done by placing the resistor in either the R29 or R30 position which has negligible resistance of 0 Ω. R30 connects the RF to the U.FL while R29 connects to the copper antenna. The U.FL connector is used for conducted testing of the RF. The HCI Tester Tool can be used to test basic RF functionality on this board.
