I do not understand where the "DISK K" memory is. Is it on the Microprocessor or on the MicroSD?

Re: usage

when I plug in the camera removable disk K shows up under computer in windows explorer.

However, using properties it says it has 80 KB which is not the size of the SD card.

I tried UART1 and the transmitter works correctly. So, I can use UART1 instead of UART3.
