New toy,
Pudu Food delivery Robot.
Doom runs fine on its internal Android RK3399 NanoPC-T4
Basically an over engineered Hoverboard with two RealSense D435 3D Cameras and Lidar

Finally there is DOOM on a Cooking Pot...
Nice hacking challenge of a way over-engineered "Smart-device"!
Inside we can find 4 SoC's from 4 companies:
Heat control via STM32F031
Input button via PIC18F8..
Wifi via ESP32
Main FW Renesas 400Mhz ARM A9

Aha! Mystery solved, the mentioned chip is actually the Display driver
The main SoC is the one next
The DA14535 with a 24 Pin case
https://renesas.com/en/products/da14535
This explains why the firmware is so similar to the DA14585^^ Not a clone
This opens up everything for a custom firmware
Crazy that the Smart BLE Ring with a Matrix Display is real🤪
But something is strange this claimed unknown PAR2860 SoC(If that is really inside the ring) looks very much like the firmware of the 7 Segment Ring (DA14585 SoC) but is still different.
maybe a cloned DA14585?
