For this second iteration, I have selected two HATs - a Pirate Audio Headphone Amp HAT with LCD display and four buttons, and an uninterruptible power supply board with battery. I swapped out the separate audio DAC hat and display/button hat when I found the volume level too low on the raspiaudio DAC hat for my purposes. The Pirate Audio hat should alleviate this issue and slightly simplifies things overall. However, it is missing the five-way tactile switch that the first iteration had and which I planned on using extensively, so I'm also adding in a five-way tactile switch separately on a small breakout board, and I'll wire the breakout board to some open GPIO pins.

*UPDATE* on the five-way tactile switch: after initial tests, it is only registering the directional button presses if it is also actuated firmly enough to register the center button as well. I will be trying a replacement switch to see if that helps.
The other hardware consists of a raspberry pi zero w board, a 32gb micro sd card, a micro-usb to usb-a plug cable, and a 256gb usb flash drive. The flash drive will be the music library storage and will be externally accessibly, should I want to remove it to modify the library contents on a system with a faster storage bus going for it. also, I could carry around a tiny fake pleather cassette carrying case that had a couple dozen usb flash drives in it and have literally terabytes of high quality music at my disposable. tres chic!
