A few days ago I took your KiCad PCB and had 15 made. Yes I removed your
TM logo like you asked =) This is just for some friends and myself. It
seems the SPI is end of life but there is a new one.

Would this one work? Of course 4MB is very small. My Debian keyring is
at least 10x that size. Is there a SPI that will fit the FST-01G PCB
that is maybe bigger then 4M? This is mostly to experiment with.

All the best
