Powered by a rechargeable Li-ion battery, the motion controller provides ‘all day’ game play between recharge, thanks in part to the ultra low power characteristics of the nRF52832 SoC. The 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.
“The decision to select the nRF52832 SoC came down to its memory and power consumption, performance, and of course its Bluetooth LE capabilities,” says Franklin Lyons, Merge VR Founder. “The availability of open-source code from the GitHub and Nordic websites was also very important to us, as is the overall relationship we have with Nordic Semiconductor.”
