I am going to order a Tone Board to use with my VIM3 Basic and I want to confirm that I will be able to play files from the Micro SD card on the VIM3 and output through the Tone Board to the RCA jacks.
EDIT: Looking at this graphic from the Tone Board user manual it looks like I can do what I am asking about but confirmation would be nice.
I have a similar question, but I will use Khadas VIM3 Pro with CoreELEC and connect a Tom Board VIM version, playing songs through CoreELEC will I have a signal on the analog L / R?
If I am not playing anything on the VIM3 Board and I put a coaxial SPDif input signal, will I have a signal on the analog L / R from coaxial input?
One more question, using Tone Board connected with VIM3 Board through GPIO, will the power come from the VIM3 Board? Can I then use USB-C as an audio input?
