A parallel to ESP32 project for the Amiga
This carrier board is made to host the popular ESP32-DEVKIT-V1 board widely available for a few bucks on AliExpress and the likes. Powering the board can be done by taking +5V from the Amigas external floppy drive port using an Adapter and connect to the DEVKIT's Micro-USB jack.
A FileServer firmware is being developed and is available here:
