Overview
2.4GHz Mini Flexible WiFi Antenna with uFL Connector is a lightweight external antenna for wireless modules and boards that use a uFL / u.FL / IPX / IPEX antenna socket. It features a 100mm cable, a flexible antenna body, 4dBi gain, and 50 ohm impedance for practical use with 2.4GHz WiFi hardware.
This antenna is suited for devices operating in the 2.4-2.5GHz range, and the supplied connector means no extra adapter is needed for compatible uFL-equipped boards. Its omni-directional radiation pattern and linear polarization make it a handy choice for embedded wireless projects where a small, movable antenna is preferred.
Important: this is an external antenna, not a WiFi module. Compatibility depends on your hardware having a matching uFL connector and support for an external antenna. Guide references mention use with products such as uFL versions of the Adafruit ATWINC1500 WiFi Shield and QT Py ESP32-S2 boards.
