From the project

Versão da Franzininho para teste e validação do ESP32-S2

The Franzininho WiFi Developer Edition is a development board designed to evaluate ESP32-S2 modules (WROOM and WROVER) and to support the development of the next generation of Franzininho boards.

The Franzininho project was created to help people develop skills in electronics and programming through DIY (Do-It-Yourself) activities, aligned with the maker culture in Brazil.
