Extends IMU Basic with BLE GATT services for real-time accelerometer and gyroscope data streaming over Bluetooth LE.
-
PPG Basic (PoC)
MAX86141 optical sensor bring-up firmware for validating PPG signal acquisition, LED control, and FIFO data logging.
-
PPG BLE (PoC)
Extends PPG Basic with BLE streaming for real-time heart-rate, SpO₂, and biometric signal transmission.
Overview¶
The KuoQuo Pivot Smart Ring proof of concept is a wearable development platform built for rapid prototyping of next-generation smart ring experiences.
Powered by the Renesas DA14531 BLE SoC, the platform integrates motion tracking and biometric sensing into a compact and modular system for wearable experimentation and development.
Goals¶
- Validate ultra-low-power wearable operation
- Experiment with motion and gesture recognition
- Enable heart rate and biometric sensing
- Support BLE-connected wearable applications
- Provide an open platform for firmware and hardware prototyping
