Customer:
Does the microSD Breakout (SKU 333050) work with 3.3V Vcc? If so, do I need to open JP1 and close JP2?
Can the microSD Breakout work with a 64GB microSD card formatted as FAT32? Some formatters can format cards larger than 32GB as FAT32.

Jesam li dobro razumio da microSD čitač kartica breakout (SKU: 333050) može raditi i sa 3,3 V Vcc?
I da u tom slučaju treba prekinuti JP1 i kratkospojiti JP2?
Ako je to tako, predlažem da to spomenete u KKM: MODUL ZA SD KARTICU u dijelu KAKO POVEZATI?
Bi li microSD čitač kartica breakout mogao raditi sa 64 GB microSD karticom ako bi ona bila formatirana u FAT32?
Čini mi se da neki formateri mogu formatirati i kartice veće od 32 GB u FAT32 format.

The microSD Breakout can work at 3.3V and no special connection changes are needed.
It should work with a 64GB card, but larger than 32GB is not recommended for FAT32. I found an interesting article about why 32GB was chosen as the FAT32 limit: https://www.easeus.com/knowledge-center/the-thinking-behind-32gb-windows-format-limit-on-fat32.html - it also contains a tutorial on how to work around this.

microSD čitač kartica može raditi na 3V3 i ne treba se ništa drugačije spajati.
Mislim da bi mogao raditi sa 64gb karticom, ali više od 32 nije preporučeno za FAT32. U istraživanju sam pronašao ovaj zanimljiv članak koji govori o tome zašto je 32GB izabran za limit FAT32-a https://www.easeus.com/knowledge-center/the-thinking-behind-32gb-windows-format-limit-on-fat32.html - ovdje se nalazi i tutorial kako to zaobići.
Customer:
Thank you for the answer - the voltage drop across the regulator is small enough that it does not cause problems.
Original message (Croatian)
Hvala na odgovoru, dakle pad napona na regulatoru je dovoljno mali da ne pravi probleme.
Soldered Support:
All our breakouts are designed to work with both 3.3V and 5V boards due to the regulator and level shifter.

Nema na čemu, zbog regulatora i level shiftera, svi naši breakouti su napravljeni da mogu raditi sa 3V3 pločama i 5V pločama.
