+@brief       Support for the Adafruit Feather nRF52840 Sense
+
+### General information
+
+[The Feather nRF52840 Sense][feather-nrf52840-sense] is a development board
+from Adafruits Feather board family. It is very similar to the [The Feather
+nRF52840 Express][feather-nrf52840] but comes with more sensors.
+
+It provides native USB support, Bluetooth
+Low Energy and IEEE 802.15.4 support via the nRF52840 MCU.
+

+[top-down view]: https://cdn-learn.adafruit.com/assets/assets/000/089/096/original/sensors_Feather_Sense_top.jpg
+
+### Flashing, Bootloader, and Terminal
+
+Refer to [The Feather nRF52840 Express
+documentation](https://doc.riot-os.org/group__boards__feather-nrf52840.html) for further details.
+Both use the same flasher, bootloader, and terminal settings.
