In order to use the SD card, we need to decide which filesystem will be used.

Currently I see two options:

FAT32 LittleFS
➕ major OS support ➖ not supported on major OS
➖ complex ➕ simple
➖ not power-loss resilient ➕ power-loss resilience
➖ not optimized for SD cards ➕ dynamic wear leveling

There are also other options such as JFFS2 or YAFFS.

WSL2 should add full linux system call compatibility to windows 10 so FUSE should work source, hopefully littlefs-fuse will too. It won't be "out of the box" support but better than nothing.

I'm +1 on FAT32 because of the OS support.
Are there other goals of including the SD card support that may sway me towards a different FS?
