2x8W at 4 Ohm TPA3110 Class-D Audio Amplifier Board
what is J8 for? where can i connect a pot for gain control? thanks
The PE description says the power supply can be a maximum of 16 volts while the Sure users manual states a maximum of 19 volts. Which is correct? If the Sure manual is correct, would a 19.5 volt supply be safe to use?
I'm thinking of a project using this board and I may want to throw a 4 ohm speaker on one channel and an 8 ohm on the other. Is that a terrible idea, or will that work out?
There is nothing wrong with doing this on this amplifier.

Are the J1,J2 sockets for input (same as the 3.5mm jack on PCB)? If so, which is L/R? Same with Output, which channel is Ch 1/2 (L,R)? I'm planning on using sig input directly from a USB bluetooth receiver, powered by a step-down DC regulator (12v to 5v).
Yes, J1 and J2 are the inputs. J1 is Left and J2 is Right. J3 is Left output and J4 is Right output.

What is the idle current rating of this amp?
Sorry about that. Downloaded the user manual and it is 20ma with a 12VDC supply. Very good for battery operation.
