Bravechip, a developer of chiplet chip-level solutions for the AIoT (Artificial Internet of Things), has launched a suite of modules based on Nordic Semiconductor’s next generation nRF54L15 ultra-low power wireless SoC. The modules are designed to help developers of smart rings bring new products to market faster, while providing a compact yet powerful solution with extended battery life.
The 5 by 5 mm ‘BCL603S2H’ smart ring chiplet integrates the nRF54L15 SoC to provide Bluetooth® LE wireless connectivity between a smart ring and the wearer’s smartphone. In addition to the connectivity, the Nordic SoC’s Arm® Cortex®-M33 processor is clocked at 128 MHz, and a RISC-V coprocessor runs software-defined peripherals while handling time-critical tasks, together with 1.5 MB non-volatile memory (NVM) and 256 KB RAM, this ensures the Bravechip chiplet has ample processing power for running a host of integrated sensors that enable smart ring functionality.
Five different variants of the module are available, with the base model’s sensors providing heart rate, blood oxygen, body temperature, exercise, sleep, and stress metrics, while the top end module also provides medical-grade Pulse Wave Transit Time (PWTT) blood pressure monitoring and ECG data. Additional functionality depending on model includes gesture recognition, touch interaction, NFC, vibration alert, and a microphone.
“Thanks to Nordic’s next generation nRF54L15 SoC there is no limit to the functionality smart ring developers can provide to the end user with the BCL603S2H chiplet,” says Jin Zongming, CEO, Bravechip. “In addition to medical-grade health monitoring, it supports gesture control of smart glasses, smartphones, and smart home devices, as well as touch control of a smartphone camera or music. In-built NFC powers payment functionality, the microphone supports voice recording, while the haptic sensor enables message reminders. From a single smart ring anything is possible.”
