How to use the microSD card of trezor Model T?

Hi @BullishGo

Have a look at the manual

Is SD card just for protection? Are there other uses?

If you use this function, do you need this firmware Release python/v0.12.4 · trezor/trezor-firmware · GitHub Is there a specific firmware replacement tutorial?
