Hi @oortgiesenrien. Thanks again for the link to the reference board. I've actually ordered one from Digikey, both because it looks promising and the other board I ordered is literally taking a slow boat from China. I should have the Infineon board early next week.In the mean time, I've been perusing the documentation. IMO, the MA12070P's datasheet leaves a lot to be desired. Documentation for the reference board is also rather sparse. But, having worked as an engineer in the industry for more than 30 years, I'm used to sub-par documentation and am confident I can make it work.Will report back. Thanks again.
I used the Adafruit 20W amplifier (PID 1752). I2C control for volume, 3.5mm stereo input. I have one. Not a bad unit.
