Next generation smart ring integrates Nordic’s nRF54L15 SoC delivering unparalleled processing and power consumption performance
IDO’s IDR01 smart ring integrates nRF54L15 SoC to supervise host of sensors and power seamless wireless connectivity
Smart wearables company, IDO, has launched its first ever smart ring, redefining what is possible from health and fitness tracking wearable technology using Nordic Semiconductor’s next generation of ultra-low power wireless SoCs. The ‘IDR01’ is based on Nordic’s nRF54L15, that doubles the processing power and triples the processing efficiency of the previous generation of SoCs, enabling the smart ring to combine a host of powerful sensors to deliver precise health insights, early warnings and personalized guidance.
The IDR01 smart ring integrates three built-in sensors—a PPG sensor, an accelerometer, and a skin temperature sensor—each designed to monitor and track the user's health status in a unique way. The heart rate sensor provides highly accurate heart rate monitoring data, the accelerometer tracks physical activity in real time, recording daily steps and exercise intensity, while the skin temperature sensor regularly measures skin temperature to assist in overall health monitoring. The data is available for review via IDO’s ‘VeryFit’ companion app.
Advanced processors support smart ring functionality
The nRF54L15 features an Arm® Cortex®-M33 processor clocked at 128 MHz, a RISC-V coprocessor for running software-defined peripherals while handling time-critical tasks, together with 1.5 MB non-volatile memory (NVM) and 256 KB RAM. This ensures the IDR01 smart ring has ample processing power for running the running the integrated sensors that enable smart ring functionality.
We selected Nordic’s nRF54L15 SoC for the IDR01 smart ring because of its outstanding overall characteristics

“Thanks to the nRF54L15 SoC’s multi-core architecture, IDR01 can support real-time tracking of 18 different sports and monitors your performance during every workout, making it the most comprehensive sports smart ring available,” says YanXiong Zhu, CEO, Shenzhen DO Intelligent Technology Co., Ltd. “It calculates energy reserves using heart rate variability, blood oxygen, breathing rate, and your daily routine—helping you train smarter and avoid overexertion. Beyond fitness, IDR01 tracks health metrics like sleep quality, blood oxygen saturation (SpO2), stress levels, and skin temperature.”
In addition to the Nordic nRF54L15 SoC’s efficient MCU, its new ultra-low-power 2.4 GHz radio enables significantly lower power consumption for typical Bluetooth® LE use cases, along with up to 8 dBm TX power and -96 dBm RX sensitivity. This enables the IDR01 smart ring to support up to five days of battery life in normal usage between recharge from its 17.5 mAh lithium cell.
nRF Connect SDK accelerates product development
“We selected Nordic’s nRF54L15 SoC for the IDR01 smart ring because of its outstanding overall characteristics,” continues Zhu. “By leveraging its powerful processing capabilities, ultra-low power consumption, larger memory capacity, and high operational efficiency, the IDR01 achieves significantly extended battery life. This enables developers to create products more efficiently.
“Furthermore, Nordic provides high-quality reference designs and development tools, coupled with robust and responsive technical support that makes the development process more efficient and convenient. The nRF Connect SDK was instrumental in our development process.”
