Nordic Semiconductor nRF21540 Development Bundle (DB) | Datasheet Preview

Nordic Semiconductor's nRF21540 DB consists of the nRF21540 development kit and the nRF21540 evaluation kit. The nRF21540 development kit contains the nRF21540 RF FEM and has two antenna ports with chip antennas and additional SWF connectors for direct RF measurements. The RF FEM is connected to and controlled by the nRF52840 advanced multi-protocol SoC. The nRF21540 development kit 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. The nRF21540 EK can connect to lab equipment via SMA connectors to monitor the RF front end module’s performance. The nRF21540’s gain control, antenna switching, and modes are controlled via GPIO or SPI or a combination of both, accessible through the Arduino Uno Rev3 compatible headers.
