The new ‘H03 Pro-N’ smart sportswatch from Trasense International uses Nordic Semiconductor’s nRF52832 SoC to wirelessly report a range of exercise metrics.
Weighing 54g and with a 42 by 10.2mm form factor, the water resistant H03-Pro-N employs a rechargeable 100mAh Li-Poly battery that provides up to 50 days standby time between recharges, thanks in part to the ultra low power consumption of the nRF52832 SoC. The nRF52832 SoC has been engineered to minimize power consumption with features such as the 2.4GHz radio’s 5.5mA peak RX/TX currents and a fully-automatic power management system that reduces power consumption by up to 80 percent compared with Nordic’s nRF51 Series SoCs. The result is a Bluetooth LE solution which offers 58 CoreMark/mA, up to twice as power efficient as competing devices.
Nordic’s nRF52832 Bluetooth LE SoC, a member of Nordic’s sixth generation of ultra low power (ULP) wireless connectivity solutions, combines a 64MHz, 32-bit ARM® Cortex® M4F processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT™ and proprietary 2.4GHz RF software) featuring -96dB RX sensitivity, with 512kB Flash memory and 64kB RAM. When launched, the SoC was the world’s highest performance single-chip Bluetooth LE solution, delivering up to 60 percent more generic processing power, offering 10 times the Floating Point performance and twice the DSP performance compared to competing solutions.
“One of the key reasons we selected the nRF52832 SoC was its multiprotocol support which dramatically reduced the time we had to spend in the development process,” says Shawn Hsu, Trasense Assistant to the CEO. “The ability to perform over-the-air firmware updates has also saved us a lot of time in software development.”
