New Products Based on Nordic nRF51822


BLE Nano & MK20 USB board

BLE Nano is the smallest BLE development board in the market
only 18.5mm x 21.0mm



Common Features

Nordic nRF51822 core

  • ARM Cortex-M0 32-bit SoC at 16MHz
  • Ultra low power consumption
  • 256 KB Flash, 16 KB RAM
  • BLE Peripheral role
  • BLE Central role (will be available later by software update)
  • GPIO pins reconfigurable (I2C, SPI, UART, Input, Output, Analog, PWM)
  • J-Link SWD interface


Freescale MK20 companion chip

  • Provide USB interface
  • Support mbed CMSIS-DAP


Development Platforms & Libraries

  • RedBearLab nRF51822 library for Arduino IDE
  • mbed online IDE and mbed BLE API
  • Nordic BLE SDK for Keil and GCC


Over-The-Air Device Firmware Upgrade (OTA-DFU)

  • This feature allows application, protocol stack or, application and protocol stack to be updated wireless, over the air
  • OTA-DFU can be initiated from a Bluetooth Smart Ready mobile device such as a smartphone or tablet, or from another internet-enabled device such as a Bluetooth Smart Ready PC


Nordic nRF Sniffer

  • Near real-time display of Bluetooth Smart packets
  • Powerful display filers and search available through Wireshark
  • Learn more about BLE and debug your application using the nRF Sniffer

RedBearLab nRF51822 Library for Arduino

Users can develop nRF51822's firmware through Arduino IDE with our nRF51822 library and define their own BLE Services & Characteristics within the sketch

We develop our board and bootloader to be fully integrated with Arduino programming environment; users could compile and upload their sketches to our boards from Arduino IDE through USB seamlessly as if they are working with an actual Arduino board

Sample sketches

  • iBeacon
  • BLE Controller
  • Simple Chat
  • Simple Control
  • BLE_HeartRate
  • BLE_UART

**We plan to release Alpha version for registered users at the same time we ship the boards in Sep 2014, the public open-source Beta version will be released later

The Nordic nRF Sniffer is a useful tool for learning about, and debugging Bluetooth Smart applications and allows for near real-time display of Bluetooth Smart packets. It helps identification and fixing of issues by allowing developers to see what is happening on-air. Additionally, this application allows you to save nRF Sniffer capture files of your application's Bluetooth Smart link.
