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
