Hi all, I'm using the MicroPython for a modular project.
I would like to use an I2C chip in the daughter boards, where that daughter each board has a unique serial number. Will have a Motherboard, and connected to it many other daughter boards. These daughter boards need to be licensed before use with motherboard. So I'm using a I2C bus between Motherboard and all other boards, where motherboard check if that serial number on the daughter boards are licensed to works works with motherboard. I see a chip like this: https://br.mouser.com/datasheet/2/268/2 ... 577009.pdf
But I would like know if you know another I2c chip better for this use case.
Thank you in advance.

Re: I2C chip Unique Serial Number
That seems a good solution.
If you want to save the hassle of writing a driver, drivers for I2C EEPROM chips may be found here. That particular chip hasn't been tested: you could either use a supported chip or check whether yours is compatible.
