M5Stack has released its new StopWatch development board, powered by the ESP32-S3. It includes everything you need to build your own stopwatch, clock, wearable device, or any other portable embedded project.

The board also comes with impressive factory firmware that showcases many of its built-in features.

In this video, I'll take a look at the hardware, go over its specifications, demonstrate the factory firmware, and show you my own custom stopwatch application built with Arduino and LVGL.
