[PROJECT] JAMMA-Pi
-
While I'm waiting for @ian57 to look at the problem on the repo of moving the pins, I'm going to continue with the sound section.
After investigating different options and see which speakers have the most arcade machines that are usually 8 Ohms and between 10 or 15w I think there are two clear options to choose from.
We have the TDA2003 that is a mono amplifier of 10w and option number two is the TDA2005 which is a stereo amplifier of 10w per channel and can be configured in bridging mode getting 20w mono.
The interesting thing about the second option would be in the case of MVS machines that had a stereo wiring in the jamma, could change from 20w mono to stereo 10w + 10w playing with some jumpers and have compatibility with jamma and mvs.
I'm going to prototype two amplifiers and try to configure them with the minimum number of components.
One thing that f**k me a lot is that the encapsulates are not SMD and they should be soldered by hand, they are also upright and they are very ugly, it has occurred to me to knock them down and use the PCB as a heatsink, later also It could be placed on the back of the PCB to save space.
What do you think is more interesting in terms of power? Maybe 20w is too much? The pc2jamma adapter works with a TDA2003.

@ian57 Any new? I'm working on the others parts of the circuit but the buttons are the most important.
