Thanks Pippin for your sharing and documenting efforts of your build. As I love small amps and PCP sets, I have quite some google experience on what is available. And quite some experience with 2 running sets based on the discontinued cirrus logic audio card.
To all of you I would suggest to look into the phat-beat from pimoroni too, as it also comes with a small 2-times-3-watt-amp and more. Some pros would be : the un-soldered female gpio plug to allow even smaller or versatile hardware setups. the pre build buttons to start-pause-power-skip and change volume etc. the option to add your own buttons if the pre-mounted ones are not fitting your needs. the option to use the apa102 leds to signal out, including VU meters if you feel up to it. On the other side, I have not seen PCP support for MAX98357A ( single or dual ) jet, but if that is solved you have got a cheap option to add a lot with 1 board. Please respond if you know more on this MAX98357A support. I myself will add rotary control to my builds too. As there is no substitute for the comfort of a physical knob you can rotate fast or slow to your needs. and this should be very well possible in parallel to other options like web-gui, IR , buttons and touchscreens. Thank you for your work on that software part ! For the power issue I am looking into the small UPS circuits boards from the far east ( often misspelled as USP if you google ). It should allow to power/charge a lithium cell , or set of cells, while also boosting the 3.x volts back to 5 volts for the pi and amp to run on. But as most claim to be 'up to 2 amps' and it needs to power pi and amp , I best test it myself before calling it a viable option. When tested I will come up with some feedback. Warning: experimenting with high energy batteries can result in unexpected results, fire and explosions are not impossible. And old school fuse is much cheaper than a blast from your fire extinguisher !
