The Great Search: uFL to SMA cables #TheGreatSearch #DigiKey @DigiKey #deskofladyada
(Video) Our latest RP2040 Board has an RFM69 or LoRa radio module on it, and to make it easy for folks to use external antennas for good range, we added a uFL connector. These common RF antenna connectors are good for up to 6 GHz or so, and are nearly universal.
However, for larger antennas such as those for 433 MHz or 900 MHz signals, we may want to have a large stick antenna, which is panel mounted. For those situations we’ll want to connect a standard SMA-type antenna! SMA connectors can also be on a PCB but they’re pretty big and are not SMT, so it’s common to use a uFL to SMA adapter cable. Where to get those? Why, Digi-Key, of course!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
