Redbear Labs Nano v2¶
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.
- 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 BLE Nano v2 board configuration supports the following hardware features:
|NVIC||on-chip||nested vectored interrupt controller|
Connections and IOs¶

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¶
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.
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.
