Nordics nRF51 series evaluation kit to test wireless sensors

ULP (Ultra low power) RF specialist Nordic Semiconductor has launched a low cost, battery-powered evaluation kit for its latest nRF51 Series 2.4GHz ULP ICs that supports real-world environmental testing of ANT/ANT+, Bluetooth low energy (including Bluetooth Smart), and proprietary 2.4GHz ULP wireless sensors and accessories.   The nRF51 Series evaluation kit is applicable to both of the first two ICs to debut in the nRF51 Series: the nRF51822 multiprotocol Bluetooth low energy / 2.4GHz proprietary RF SoC, and the nRF51422 ANT/ANT+ SoC.   Compatible with a range of application examples contained within Nordic's nRF51 Series SDK and comprise nRF51x eval board (with all components mounted single-side), nRF51x USB dongle, coin-cell battery compartment, PCB strip antenna, Segger J-Link de-bug capability, USB port for computer link-up, 32 I/O header pins for access to all GPIOs, two miniaturized buttons plus two miniaturized LEDs available for user-defined functions, and current measurement pins.   The kit brings new design freedoms to the prototyping and initial development of ULP wireless product applications. With dongle-based evaluation set-up a development engineer is now freed from their test-bench set-up to write code, test, and perform in-situ evaluations anywhere. Such freedom is essential for a whole range of early-stage application evaluations and testing and will benefit all nRF51 Series-relevant ULP wireless applications: from engineers prototyping multiple body-worn sensor network products all the way through to industrial measurement and control systems.   "The challenge is to date the development and eval tools available for prototyping ULP wireless nodes have tended to be designed for desk-based testing, while being quite costly when purchased in multiple unit numbers," comments Geir Langeland, Nordic Semiconductor's director of Sales & Marketing. "What these new nRF51 Series eval kits will do is to allow developers to prototype and test ULP wireless sensors and accessories under real-world environmental operating conditions in a cost effective way that supports rather than hinders them."   Nordic Semiconductor
