This is an inner thread (outer nut) adapter that will connect to any of our wireless boards or interface cables and allow you to use an antenna/cable that has an outer thread configuration.

You should not need this adapter with any of our antennas or dev boards. These adapters are listed only to help SparkFun users that have rare or odd antenna coupling needs. Be sure to check out the SMA connector tutorial here for more information on SMA connectors.

Supported Connections: Any RP-SMA or SMA antenna, cable, or connector that uses an outer thread design. All Spark Fun antennas use an inner thread (outer nut) design.

This is an adapter that converts an RP-SMA board to an SMA antenna. The adapter will connect to any of our 2.4GHz wireless boards or interface cables and will allow you to use an antenna/cable with an SMA connection.

You should not need this adapter with any of our antennas or dev boards. These adapters are listed only to help SparkFun users that have rare or odd antenna coupling needs. Be sure to check out the SMA connector tutorial here for more information on SMA connectors.

That is a GPS chip antenna. Itty-bitty! And we were just as surprised when it picked up just as many satellites as the larger ceramic antennas. The PDOP and VDOP (dilution of precision) of these chip antennas are greater than their ceramic siblings and the gain is not as great (to be expected), but heck, if you can get a lock with this little guy, who cares?

PCB edge mount - SMA RF connector. Perfect for prototyping with the GPS and Cellular devices that require an antenna connection. These connectors have a female signal pin and will correctly mate with the original SMA type antennas.

Documents: Datasheet
Supported Antennae: Connects to the cellular and GPS antennas with standard SMA termination.

Be sure to check out the SMA connector tutorial here for more information on SMA connectors.

PCB edge mount Reverse Polarized - SMA RF connector. Perfect for prototyping with our RF ICs. This is a standard edge connector. The thickness between pins is 0.063" so that it can slide sideways onto a PCB. See the mechanical drawing to create your footprint.

The FCC is moving towards Part 15 compliance. All this means is that all the SMA RF connectors are changing gender. Really annoying for those of us who need to mate an antenna to an RF device. The FCC gender change was instituted to prevent home users from damaging RF equipment (think home WiFi) when screwing on an antenna. If all antennas are female, there is no way to damage the center connector. However, you have to be very sure now what kind of SMA connector you need.

Documents: Datasheet
Supported Antennae: Any antenna that follows the reverse polarized SMA convention. These are the most common 2.4GHz antennas you'll find.

2.4GHz ceramic chip antennas. Very small antennas that work nicely with the Nordic ICs. Don't expect these little guys to perform as well as their ~2" rubber duck counter parts, but then again, these will squeeze onto any PCB layout.

Dimensions: 2.2x6.5mm
