On-Board Antenna & External Antenna Options
The BeagleBone Enhanced (BBE) is manufactured as standard with a U.FL connector to allow for an external antenna to be connected.
Depending on the version you have purchased you may need to modify the board to use the U.FL connector.
The blue highlighted resistor is for the on-board antenna option and the yellow highlighted resistor is for the U.FL connection. In order to use the U.FL connector the 0402 0R0 resistor need to be moved to the yellow highlighted position.
