Redbear Labs Nano v2
####################
Overview
********
The Nano v2 is a development board equipped with Nordic's next generation nRF52832 Bluetooth Low Energy SOC.
This board was designed as a 'drop-in' replacement of BLE Nano with exactly the same form factor.
This board will be available for Kickstart backers on February 2017.
It is also available on Redbear store.

Hardware
********
- nRF52832 SoC is built around a 32-bit ARM Cortex-M4F CPU with 512kB flash + 64kB RAM
- 11 x Digital I/0
- 1 UART with hardware flow control ( 4 I/O pins occupied )
- 1 I2C ( 2 I/O pins occupied )

The DAPLink USB board acts as a dongle. DAPLink debug probes appear on the host computer as a USB disk.
It also regulates 5V from USB to 3.3V via the onboard LDO to power Nano v2.
Programming and Debugging
*************************
Applications for the ``nrf52_blenano2`` board configuration can be built and
flashed in the usual way (see :ref:`build_an_application` and
:ref:`application_run` for more details).
Flashing
========
To flash an application, you'll need to connect your BLE Nano 2 with the
DAPLink board, then attach that to your computer via USB.
.. warning::
Be careful to mount the BLE Nano 2 correctly! The side of the board
with the VIN and GND pins should face **towards** the USB
connector.
Now build and flash applications as usual. Here is an example for the
:ref:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: nrf52_blenano2
:goals: build flash
Debugging
=========
After mounting the BLE Nano 2 on its DAPLink board as described above,
you can debug an application in the usual way. Here is an example for
the :ref:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: nrf52_blenano2
:maybe-skip-config:
:goals: debug
