We’re sending ESP-Mosaico to a few early builders. What would you make with it?

We’ve been working on ESP-Mosaico, a new modular development board built for Coding Agents, and we’re ready to put a few early units into developers’ hands before the public launch.

We’re looking for a small group of makers, developers, and technical creators who want to experiment with it, push it in unexpected directions, and tell us what works and what doesn’t. Try Chat Coding, push the hardware, connect modules, build across multiple devices, or do something we haven’t anticipated yet...

If you have an idea you’d like to explore with ESP-Mosaico, we’d love to hear it.

And even if you’re not applying, I’m curious:

If a Mosaico landed on your desk tomorrow, what would you build first?
