9V Battery to 2.1mm for Arduino Uno Quick view

Reference: RBD-0733

RP-SMA to U.FL Cable 150mm Adapter RF Cable

This RP-SMA to U.FL Cable is commonly used to attach WiFi, Bluetooth, or nRFxxx based devices to a 2.4GHz antenna. What makes this unassuming cable special is the slightly longer length of 150mm (compared to 100mm). We found that the extra 50mm makes all the difference when working with an enclosure. U.FL Termination RP-SMA Termination 150mm Length
