The BLE Nano v2 from RedBearLab is the smallest Bluetooth 4.2/5.0 Low Energy (BLE) development board on the market. With the included DAPLink USB in this kit, you’ll be able to deploy firmware to BLE Nano v2 even easier. At each BLE Nano’s core is a NordicnRF52832, an ARM Cortex-M4F System on Chip (SoC), plus BLE capable of running at 64MHz with ultra low power consumption. The RedBearLab BLE Nano also supports numerous different wireless devices running iOS 7/8, Android 4.3 or higher, and Windows Phone 8.1.
The DAPLink board functions as a USB dongle, accepting 5V from the USB port and regulating it to 3.3V via the onboard LDO, which can be used to power RedBearLab BLE Nano v2. When plugged into your computer, the USB board will appear as both a serial port and a removable mass storage disk.
Developing a Bluetooth Smart-enabled ‘appcessory’ (accessory device + companion application) is easier than ever. You can quickly produce prototypes and demos targeted for Internet of Things (IoT) and other interesting projects. The RedBearLab BLE Nano v2 can operate under 1.8V to 3.6V, making it able to work in conjunction with a wide variety of electronic components. Since the RedBearLab BLE Nano v2 can work as low as 1.8V, the DAPLink USB board has been designed to run at 1.8V as well. All you need to do to get the USB board to run at 1.8V is short the switch S. Then the regulator will output 1.8V instead, allowing your Nano to work with applicable components.
