Integrated Creation Identifying Key Issues
In addition to standard hardware development, the main challenge lay in achieving noise-free wireless charging while optimizing battery performance for this ESP32-based smartwatch.
Defining Our Vision
The goal was to create an environment suitable for successful firmware development, and once that stage was complete, to have a setup we could proudly showcase in our offices and on our walls. This led us to design a stand or wall-mounted enclosure for the environment.
PROJECT OUTCOME Strategies Used
The GUI was developed using SquareLine Studio, while other internal tasks were handled with RTOS. In parallel with the hardware development, we created a demo flutter app to showcase and interface with all the features this board has to offer.
Outcome Delivered
The result was a minimalist yet sleek wall-mounted or desktop display, capable of continuously delivering a full test experience of the smartwatch’s features and OS in a fully functional form.
