Built for Coding Agents, ESP-Mosaico is a modular development board powered by ESP32-S31. It takes AI agents beyond software and into the physical world, enabling them to create, deploy, test, and iterate on real hardware. Expandable modules and multi-unit tiling give AI agents more ways to create, while Chat Coding and Vibe Coding give you intuitive ways to turn ideas into working physical devices.
If AI can keep changing software, why should hardware stay fixed?
In embedded development, ideas often evolve faster than the hardware around them. Add a camera, sensor, button, light, or motor, and suddenly you’re back to rewiring, reconfiguring, or rebuilding parts of the system.
ESP-Mosaico takes a different approach. Start with an ESP32-S31-powered Core, add the modules your idea needs, and rearrange the hardware as the project evolves. Multiple Mosaico devices can also work together, so physical layout itself can become part of the interaction.
On the software side, Chat Coding lets you describe what you want and turn it into a working application. Vibe Coding goes further, letting an AI coding agent work across code, deployment, testing, and real-device feedback.
The goal is simple: make the path from an idea to working hardware much shorter.
We’d love to hear from the Product Hunt community: What would you build if your hardware could evolve as quickly as your idea?

Who hunted ESP-Mosaico?
ESP-Mosaico was hunted by Ethan Lin. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.

Hi Product Hunt! 👋
We built ESP-Mosaico around a simple question:
If AI can keep changing software, why should hardware stay fixed?
