Getting informations from the board
The only element that as interest on the board is an ATMEL 646 24C02BN SU18 chip, if we browse a bit on the internet we can find some documentation about it

As the chip doesn’t have any marks on it to determine the first pin, we had to do some tests and look at the chip on the board and the datasheet we found.
Here is the result :
Setting up the EEPROM reader
Now that we know how the chip is set on the board, we can try to dump the EEPROM using a CH314 reader and the software that goes along
Data Analysis
It appears to be multiple sections of valuable informations in the data stored.
The fact that most of the elements that are not “Random” are 00 or FF appears to us as buffer to properly separate every pieces of informations
Data exploitation
ℹ️
We haven’t been able to find any documentation about what is stored in this chip, therefor we can’t really exploit it.
