Design

Front

This tiny microcontroller is the smallest I’ve ever seen—it's as small as a Ctrl key! Powered by the ESP32-S3FN8 chip, it supports M5 UIFlow and graphical programming, making it perfect for creative IoT projects.

Back

The IO interface spacing supports both 2.54mm and 1.27mm, offering flexibility for different applications. It features 23 IO interfaces (G0-G46) for expansion. The entire development board is built with immersion gold plating, ensuring durability and reliable performance.

Inside

The circuit board is compact and efficiently designed, with no wasted space. What’s exciting is the LED located in the upper-right corner. I can’t wait—let’s light it up!

 

   

How to Use

M5Burnner

Connect the StampS3 to your computer, open M5Burner, and select StampS3. Download UIFlow 2.0, enter your WiFi SSID and password, and start the burning process.

 

UIFlow2.0

Once the device is online, we can upload code to the StampS3 via Wi-Fi.

 

Graphical Programming

Initialize the RGB hardware by customizing the IO to 21, setting the number to 1, and the type to SK6812. Then, configure RGB21 with three colors.
