I am now making a workaround. I connected Nano+SD module to Mega 5V so that Mega is now powering on my Nano.. Well it's a strange idea, but all I need is background music with no control over it. Nano plays music by itself using SD library and Mega works with LCD using UTFT_SdRaw. Too bad I have to connect 2 SD cards now :D. My power bank is 5V/1A.

Hello there. Thank you for your guide, I made it using Uno R3 and SD module and it worked. Now I face a little problem with Mega 2560 + LCD screen with SD card reader. I am using library UTFT SdFat and UTFT_SdRaw to display images from SD card on LCD screen. TMRpcm library needs SD library to work but when I include it I get lots of errors that point to SD and SdFat. When I upload your code Mega 2560 plays from SD card without any problems. Is there any way to make TMRpcm work on SdFat only?
