Why did you make it?

We wanted to create something that combines functionality with creativity. Standard boards are great, but we thought: why not make them more visually appealing? ESP32-S3 Youth started as a fun project for ourselves, but we realized it could inspire others to add a bit of personality to their electronics. It’s a tool for serious work with a touch of fun.

From the Developer: Personally, as the developer, I am proud of this board. I invested a lot of time and effort into its design, going through several unsuccessful prototypes before finally achieving a result that satisfied me.

The price reflects the small production volumes — the more boards we produce, the lower the cost per unit. With your support, we hope to lower prices over time.
