The board has a PCB antenna for the 2.5 GHz ISM Band, for stand alone operation on the Camp Area. **For other frequencies the use of an external antenna is highly recommended.** | The board has a PCB antenna for the 2.5 GHz ISM Band, for stand alone operation on the Camp Area. **For other frequencies the use of an external antenna is highly recommended.** | ||

<note important>**When soldering an antenna or SMA connector, a resistor (R315, 0 Ohm) must be turned 90 degrees or replaced with a bridge, connecting the RF line on the left to the SMA connector pads on the right**</note> (then the 0 Ohm resistor will be sitting on the R314 pads; R314 and R315 share the upper left pad). Use 2 soldering irons - so you can easily move the little resistor. | <note important>**When soldering an antenna or SMA connector, a resistor (R315, 0 Ohm) must be turned 90 degrees or replaced with a bridge, connecting the RF line on the left to the SMA connector pads on the right**</note> (then the 0 Ohm resistor will be sitting on the R314 pads; R314 and R315 share the upper left pad).
