@quinn yeah! it's various things, sometimes including a microcontroller chip of sorts (ESP32 best), but just whatever sparks my interest really
for my last batch i actually did a write-up of what was in there, hoping to continue that into the future as well (and have updates when assembled) https://cthu.lu/projects/JLC-2020-12-21/
the Nessie PCB is older, and needs a redesign because the chip consumes too much power, some more info at https://social.pixie.town/@f0x/103472319487529921
@f0x awesome nice, now I have another rabbit hole on my list 😅
