+@brief Support for the Seeed Studio XIAO nRF52840
+
+### General information
+
+The [XIAO nRF52840][seeedstudio-xiao-nrf52840] (formally known as XIAO BLE)
+is a development board from Seeed Studio's XIAO board family.
+
+It provides native USB support, Bluetooth
+Low Energy and IEEE 802.15.4 support via the nRF52840 MCU.
+
+
+
+[seeedstudio-xiao-nrf52840]: https://wiki.seeedstudio.com/XIAO_BLE/
+
+### 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.
+
+Example with `hello-world` application:
+```shell
+make BOARD=seeedstudio-xiao-nrf52840 -C examples/basic/hello-world flash term
+```
