NRF21540-DB

NRF21540-DB is a development bundle for the nRF21540 RF front-end module (FEM) for 2.4 GHz range extension. The nRF21540 DB consists of the nRF21540 development kit (DK) and the nRF21540 evaluation kit (EK). The nRF21540 DK is the perfect tool to develop products that require the range extension capabilities or link budget improvements provided by the nRF21540 RF front-end module (FEM). The nRF21540 EK can connect to lab equipment via SMA connectors to monitor the RF FEM’s performance. The nRF21540 DK contains the nRF21540 RF FEM and the nRF52840 SoC and has two antenna ports with chip antennas and additional SWF connectors for direct RF measurements. Suitable for asset tracking and RTLS, professional lighting, smart home, industrial, toys and audio applications.
