The Gekko version of the early nanoVNAs had the solder pads for an SD card slot - look at my forum photo from almost a year ago.
I actually added a slot to mine but then sold the unit and bought a better made one (no SD pads).
/g/nanovna-users/message/223I have ordered an ST32F303 and I'm looking for the proper LCD panel so that I can convert my H into an H4.
I will add an SD slot to the PCB as well.

No for H need compile its own firmware, it have about 14kB free flash. Only Fat32 and short filenames need ~10kB (but i don`t test this for H firmware)
Also H version not have SD slot on PCB board, need add it, but this difficult for me (for my test).
