Arduino Uno shield-compatible kit for Bluetooth Smart, ANT, 2.4 GHz designs

October 29, 2014 // By Graham Prophet
Nordic Semiconductors’ low-cost nRF51 DK development kit comes in Arduino Uno shield-compatible single-board form factor - supporting a broad range of third-party Arduino shield expansion boards - and provides flexibility for product development with all key ULP wireless technologies.

The kit also supports ARM mbed for rapid prototyping and development: the nRF51DK is a low-cost development kit platform for fast, easy, and flexible development of Bluetooth Smart (formerly known as Bluetooth low energy), ANT/ANT+, and 2.4 GHz proprietary applications. Nordic has also announced the launch of the nRF51 Dongle, a highly versatile USB dongle to aid test, analysis, and development of Bluetooth Smart, ANT, and 2.4 GHz applications.

The nRF51 DK is based on Nordic's nRF51 Series System-on-Chip (SoC), a highly-integrated transceiver that combines a 2.4 GHz multiprotocol radio, 32-bit ARM Cortex M0 processor, 128 kB or 256 kB flash memory, and 16 kB or 32 kB RAM. The SoCs can support a wide range of peripherals and are available in quad flat no-lead (QFN) and wafer level chip scale package (WLCSP) options. The SoCs can support a range of SoftDevices (Nordic's SoftDevices are self-contained stacks that incorporate RF protocols and associated management frameworks) for Bluetooth Smart, ANT, 2.4 GHz proprietary, and even combinations of these protocols on a single device.

The nRF51 DK is compatible with the Arduino Uno connector standard enabling use with a broad range of third-party Arduino shield expansion boards. The nRF51 DK allows access to all device peripherals, interfaces, and I/Os. The kit has four user-programmable buttons and LEDS plus voltage and current pins to measure device power consumption.
