  Buonasera, le volevo chiedere se questa scheda di espansione universale è compatibile con la Esp32-S3 N16R8

    Dear customer,

    If you only need a board for the ESP32-S3, we recommend the OSOYOO ESP32-S3 IO Breakout Board (https://osoyoo.com/?p=61757). It is plug-and-play, super convenient, and beginner-friendly.

    However, if you often work with other microcontrollers, the OSOYOO Universal IO Breakout Board (https://osoyoo.com/?p=61699) offers stronger versatility. Note that it requires configuring jumper caps for proper voltage, making it ideal for experienced developers.

    Please feel free to contact us if you have any questions!
