@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
|
||||
```
