Oslo, Norway 2015/06/01 - Ultra low power (ULP) RF specialist Nordic Semiconductor ASA (OSE: NOD) today announces that Athlete Architect, a Boulder, CO-based technology-centered sports and fitness company, has launched Stryd, a wearable device for measuring running power. Stryd offers both ANT+ and Bluetooth® Smart (previously known as Bluetooth low energy) wireless connectivity, using Nordic’s nRF51422 multiprotocol System-on-Chip (SoC).
  
Ultra low power (ULP) RF specialist Nordic Semiconductor ASA (OSE: NOD) today announces that Athlete Architect, a Boulder, CO-based technology-centered sports and fitness company, has launched Stryd, a wearable device for measuring running power. Stryd offers both ANT+ and Bluetooth® Smart (previously known as Bluetooth low energy) wireless connectivity, using Nordic’s nRF51422 multiprotocol System-on-Chip (SoC).
  
The device’s sensors calculate run power, measured in Watts, an objective and instant measure of overall running performance unlike, say, heart rate, which can be distorted by a range of environmental factors and lags behind a runner’s actual pace, making real time analysis more difficult. Powered by a single coin cell battery, the device has a battery life of up to 12 months extended, in part, by the ultra low power consumption of the nRF51422.
  
Due to its unique multiprotocol support, Nordic’s nRF51422 allows captured data to be wirelessly sent to the user’s sports watch or iOS or Android smartphone for mid-run performance analysis, as well as tablets for post-work out feedback via a Cloud-based training platform.
  
The nRF51422 is a powerful, highly flexible multiprotocol SoC ideally suited for ANT+ and Bluetooth Smart ultra low power wireless applications. The nRF51422 integrates a 32-bit ARM® Cortex™ M0 microcontroller, 2.4GHz radio, 256kB/128kB Flash memory, and 32kB/16kB RAM on a single chip.
  
“Empowered by Nordic ultra low power wireless technology, Stryd is able to interact with runners in real time, via sports watch or smartphone, which enables real time feedback and coaching, to help runners manage their training intensity, improve their running form, and optimize their pacing, making them run better, faster, and safer,” says Stryd co-founder, Li Shang.
  
Following a successful Kickstarter campaign, Stryd will be commercially available in volume from Spring 2016.
