Franzininho Tiny Board

The Franzininho Tiny follows up on the excellent work of the Franzininho DIY. In many applications soldering is not viable, so there were frequent requests for pre-assembled Franzininho DIY boards — which was never the purpose of the DIY format.

To address this, we chose a microcontroller that maintains compatibility with the Franzininho DIY but offers more pins and comes in an SMD package.

The Franzininho Tiny has a breadboard-compatible form factor and comes fully assembled and ready to program:
