This cute little coax is a champ in our RF kit! It has a right angle female U.FL (aka I-PEX) connector on both ends. Now instead of jerry-rigging a few U.FL to SMA cables together we can go straight from one U.FL device to another. As an added bonus this coax is the nice stuff - approximately 1mm in diameter and extra flexible. The 50-ohm impedance of this cable makes it well suited for almost all SparkFun RF products including GPS, LoRa, and RFID.

Jargon buster

Plain-language definitions for the technical terms used above.

GPS
The US satellite navigation system used by GNSS receivers to calculate position and time. Support for GPS is important because it is widely available and often used together with other constellations for more reliable positioning.
LoRa
LoRa is a long-range, low-power radio technology often used for telemetry and remote sensors. It matters here because the connector and pinout are compatible with some LoRa telemetry products, even though this module uses Bluetooth instead.
RF
RF means radio frequency, referring to signals used for wireless communication and other high-frequency electronics. A low-noise, stable power supply is important for RF circuits because power noise can affect signal quality and measurements.
SMA
A threaded coaxial connector commonly used for antennas. It matters because you need antennas with matching SMA connectors, or suitable adapters, for the LTE and GNSS antenna ports.
u.FL
u.FL is a tiny snap-on antenna connector often used on compact wireless boards. A board with u.FL usually needs an external antenna, which matters if the product will be inside an enclosure or needs better antenna placement.
