@brief Support for the Adafruit Feather nRF52840 Sense
5+
6+
### General information
7+
8+
[The Feather nRF52840 Sense][feather-nrf52840-sense] is a development board
9+
from Adafruits Feather board family. It is very similar to the [The Feather
10+
nRF52840 Express][feather-nrf52840] but comes with more sensors.
11+
12+
It provides native USB support, Bluetooth
13+
Low Energy and IEEE 802.15.4 support via the nRF52840 MCU.

18+

20+
21+
### Flashing, Bootloader, and Terminal
22+
23+
Refer to [The Feather nRF52840 Express
24+
documentation](https://doc.riot-os.org/group__boards__feather-nrf52840.html) for further details.
25+
Both use the same flasher, bootloader, and terminal settings.
