With the motherboard out, we find the bottom of it rather… unspectacular at first sight. A big battery recess and all of the cable connectors set up camp here, but deeper down we spot some hidden chips:

CMJRD11G04G 16 GB NAND flash storage (likely) layered above maybe a WiFi processor

Ambiq Micro AMAP42 Apollo4 SoC

Runic RS7222 USB 2.0 DPDT analog switch (likely)

We're not in the mood to camp here with them for long, so we hurry over to more important sightseeing. Onward!
