Nordic Semiconductor nRF21540 DB Development Bundle (DB)

Nordic Semiconductor nRF21540 DB Development Bundle (DB) includes the nRF21540 development kit (DK) and the nRF21540 evaluation kit (EK) with the nRF21540 RF front end module (FEM). The nRF21540 DK is an excellent solution to develop products that require the range extension capabilities or link budget improvements provided by the nRF21540 RF FEM. Furthermore, the nRF21540 EK connects to lab equipment via SMA connectors to monitor the RF FEM’s performance.
