Hello,

 

is it normal that LF33 will be very hot in a short time when I connect a SD Card to J16? There is only the bootloader installed and after inserting SD Card -> the LCD shines a bit weaker and Core's LED switched of and it restarts after removing SD Card again. With Card inserted the core won't complete boot.

 

The core gets power via external 5V.

 

Thanks for help.

 

Greets, rio
