This repository hosts the source code and technical documentation for the SmartWatch project, developed as part of an embedded systems course. The prototype is a wearable device designed for health monitoring, motion tracking, and real-time data visualization, while seamlessly communicating with a smartphone via Bluetooth Low Energy (BLE).

- Health Monitoring: Measures heart rate and blood oxygen saturation (SpO₂) using the MAX30102 sensor. - Motion Tracking: Detects 3D acceleration and orientation with the MPU-6500 sensor. - Environmental Sensing: Captures temperature, humidity, and…

SmartWatchProject: common questions

What microcontroller does the SmartWatchProject use?

The SmartWatchProject is built around the STM32L476RCTx, from the STM32 family.

How big is the SmartWatchProject PCB?

The SmartWatchProject measures 70 × 150 mm, has 6 copper layers and is 1.6 mm thick.

How many components are on the SmartWatchProject?

76 components, from 30 distinct parts. The full bill of materials is listed on this page.

Where can I download the SmartWatchProject design files?

From the exysta/SmartWatchProject repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the SmartWatchProject design in my own project?

The repository has no license, so all rights stay with exysta. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the SmartWatchProject without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
