This guide is for adding ad SD card to a Nano AP. I will use this module: SD card module

In the platformio.ini, change the 'board_build.partitions' esp32_sdcard.csv.
Add to the build_flags -D HAS_SDCARD

-D USE_SOFTSPI

-D SD_CARD_SS=11

-D SD_CARD_CLK=9

-D SD_CARD_MISO=8

-D SD_CARD_MOSI=10

If you build it now, you'll get an error message. We need to change one more thing.

In the storage.cpp, row 22 (at the time of writing with the 1.8 and 1.9 version), change 'VSPI' to 'HSPI'.
Now upload as usual.

For the hardware side, solder the wires. Format the SD card and it should work!
