Round Display Smartwatch

Displays · Board: XIAO · Day 79 of 100

A circular GC9A01 display on the XIAO ESP32-S3 shows time and weather from NTP and OpenWeatherMap. Round-screen wearable chic.

How it works

Time arrives via NTP and weather via the OpenWeatherMap API, and the XIAO ESP32-S3 renders both onto the circular GC9A01 display. Round screens demand circular thinking: the layout wraps around the center instead of filling corners. Wearable chic with real data behind it.

What you'll learn

  • Round display rendering
  • Circular UI layout
  • NTP plus weather APIs
  • Wearable data design
