A not completed schematic, but the essentials are there. Seams like devkitC is a popular devboard but have to continue to look.
SD-card connection from this example: https://github.com/espressif/esp-idf/tree/master/examples/storage/sd_card#hardware
Have to check other sources as well.
Will change the input connector to a green screw or snap-in connector with a low profile.
Next update with a draft PCB
