I’ve made progress with my small portable music player, with the core of the player built. This uses an RPi Zero W with DAC and headphone amp daughter board total height of 3/4”/29mm. So far so good. Next step is to find a small display to use with it. I have some links to earlier discussions about which displays might work, and I’ll post them here.
The current question is, if I use a display that is only connected to the Pi only with HDMI, does this carry the touch information on HDMI?
