How to Properly Use M5Stack StampS3 for Smart IoT Projects
Here’s a fun microcontroller adventure with the StampS3 from M5Stack!
What is StampS3
The StampS3 is an IoT controller powered by the ESP32-S3FN8 chip, featuring 8MB flash memory. With a high-performance processor running at up to 240MHz, it delivers impressive computing power, perfect for embedded control modules in IoT projects.
The StampS3 includes a built-in 5V to 3.3V circuit for stable power, along with an RGB status indicator and a programmable button. It offers 23 GPIOs for expansion, accessible via 1.27mm/2.54mm spacing leads, supporting flexible usage.
Compact, powerful, and efficient, the StampS3 is well-suited for IoT applications that require reliable embedded controllers. Its flexible GPIO expansion options make it ideal for a variety of smart projects.
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.
