+@defgroup boards_nrf51dk nRF51DK Development Kit
+@ingroup boards
+@brief Support for the Nordic nRF51DK Development Kit
+
+## Overview:
+
+The nRF51 DK is a low-cost, versatile single-board development kit for
+Bluetooth low energy, ANT and 2.4GHz proprietary applications using the nRF51
+Series SoC.
+
+## Flashing the Device:
+
+The nRF51DK board is shipped with an on-board JLink debugger that doesn't work
+well with UART: the shell is only working on RX but not TX.
+
+Thus, we recommend to update the flasher ship with DAPLink as described
+[here](https://armmbed.github.io/DAPLink/?board=Nordic-nRF51-DK):
+1. Download [this firmware](https://armmbed.github.io/DAPLink//firmware/0251_sam3u2c_mkit_dk_dongle_nrf5x_0x5000.bin)
+2. While holding down the boards reset button, connect the boards USB debug
+ port to the computer. It should enumerate as `BOOTLOADER`
+3. Using a filesystem browser, drag-n-drop the firmware file to the
+ `BOOTLOADER` folder
+4. Power-cycle the board, a new DAPLink mount point should appear
+
+The programmer used to flash this board is OpenOCD.
+
+To flash the board, use the following command:
+```
+$ make BOARD=nrf51dk flash
+```
+from any application directory.
