ZSWatch is a free and open source smartwatch you can build almost from scratch – including software, hardware, and mechanics. Everything from the lowest level BLE radio driver code to PCB and casing is available for introspection or to be customised to suit your needs.In this project, the team will add interesting new capabilities such as Heart Rate and Blood Oxygen sensor hardware, create a new iteration of hardware to improve wearability, improve documentation, make it easier to upgrade, and make various improvements to the software including optimising power consumption
