Flash Frothy
Install Frothy on a compatible ESP32 or RP2040 board from your browser.
Connect the board over USB and choose its ready-made firmware. ESP32 installs directly and erases the board, including saved Frothy code. RP2040 downloads a UF2 for its RPI-RP2 drive and replaces only the firmware range. Your editor sources stay safe.
After flashing, Check Frothy sends a small status request before you continue.
