Identifying toniebox chipset

Hi guys (and gals)!

I am new to toniebox hacking (but not new to hacking/general IT), so maybe my question seems a bit simple…

How do I identify the chipset of my toniebox? I have two of them, bought quite some time ago I think one is from 2021, the other one is newer, but still 2023 tops… Both carry a sticker with “Assembled in China”.
Macvendors identify both as “Texas Instruments”, so probably both aren’t ESP32.
One has “16.02-MAN-REV1.2” near the RFID reader plug, the other one has an 8-digit number there.
Any suggestions?

Thanks in advance
Best regards

Open the box, check the chip directly.
