## Feitian OpenSK USB Dongle
|
|
|
|
### Flashing using DFU
|
|
|
|
This board is similar in hardware to the Nordic nRF52840 Dongle. You can use DFU
|
|
to flash it, instructions to enter DFU mode depend on the version of your
|
|
hardware. See
|
|
[Feitian's instructions](https://feitiantech.github.io/OpenSK_USB/). In short:
|
|
|
|
* In V1, use a paperclip to press the Reset button through the tiny hole.
|
|
* In V2, push and hold the user button for more than 10 seconds after
|
|
connecting your device.
|
|
|
|
Afterwards, you can flash your Feitian OpenSK using DFU following the
|
|
[instructions for the Nordic nRF52840 Dongle](nrf52840_dongle.md#Flashing-using-DFU).
|
|
|
|
### Buttons and LEDs
|
|
|
|
For both hardware versions, the buttons and LEDs are described in detail in the
|
|
[hardware section](https://feitiantech.github.io/OpenSK_USB/hardware/) of
|
|
Feitian's website.
