  SoC and a Sony IMX415 sensor.

Chip and memory

  listing SSC378 modules: "378DE in T3, and 378QE in MC800S5".

- Some messages give only the family, SSC378: "MC800S5 from Anjoy is the
  same imx415 but SSC378". (https://t.me/c/1809358416/275219,

Disagreements
- SoC variant: most messages say SSC378QE, but one 2024-09 message says
  "MC800S5 (SSC378DE)". (https://t.me/c/1809358416/112010,
  https://t.me/c/1809358416/108787, https://t.me/c/1809358416/217588)
- In 2024-09 Tino doubted the declared spec: "MC800S5 is declared as
  SSC378+Imx415. though i have my doubts..". Later messages again state
  SSC378QE/IMX415. (https://t.me/c/1809358416/116116,
