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.

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 )

Connections and IOs

BLE nano v2 pinout

NANO2

DAPLink board

DAP

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 Building an Application and Run an Application 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 Hello World application.

# From the root of the zephyr repository
west build -b nrf52_blenano2 samples/hello_world
west 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 Hello World application.

# From the root of the zephyr repository
west build -b nrf52_blenano2 samples/hello_world
west debug
