Other components are because some vehicles are only OBD, and no CAN bus, so they have to implement the serial comms that OBD has, which are 12V signals, so level shifting to both repond to the signals, and read the data back off them. Microcontroller is very likely just a common Chinese microcontroller with a small amount of on board flash, that then fetches the actual operating code from the flash memory and exacutes it. Likely limited RAM as well, probably less than 64k, and likely same amount of ROM as well to just communicate with the flash, with probably encrypted memory with an on chip common key, to keep the cloners away. Likely the different versions all are identical, just the key is different, to prevent you flashing the high end firmware on the base model, and getting it free, plus also allowing branding different names, while keeping the firmware safe-ish.
@@sdgelectronics Thanks, I bought one based on the recommendation but on one car it doesn't detect at all, on the other it works for basic features but can't do much besides read fault codes. No option to select car model as the user guide suggests.

Yes, other parts are probably for non-CAN OBD communication - J1850, ISO 9141-2, KWP2000.
Good insight, thanks.
I think the transistors on the input do level conversion.
Thank you for the video!👍
Cheers.
Liked the review
Just seen this video - does anyone know if this will work on a Toyota vehicle?
Does this have any advantage over a BT adapter and an app?
Nothing other than you just plug it in and it works
They must be using some generator to come up with those company names.
Can anyone share the firmware update? Looks like the manufacturer has pulled it from all the web links
No firmware available for this model yet. It's released with the current firmware.
