GPS is common but what if you need to pack your GPS receiver into a small space such as a wearable? Standard GPS antennas are much too large to strap to your wrist so what do you do? You use one of the SparkFun GNSS Chip Antennas!

SparkFun GNSS Chip Antenna Evaluation Board


The SparkFun GNSS Chip Antenna Evaluation Board makes it easy to test out various sized GPS antennas and geometries. These individual antennas can even be separated and installed permanently into a project once you select the best one for your application.

Required Materials

The GNSS Chip Antenna Evaluation Board (we’ll call it the eval board from here on out for your tongues’ sake) is possible because we have designed each antenna to have a 50-ohm microstrip. To connect, you’ll need a U.FL cable and a GPS receiver capable of connecting to a U.FL cable. You may not need everything though depending on what you have. Add it to your cart, read through the guides, and adjust the cart as necessary.
