Hi all,

Thank you in advance.

Alternatively, you can use the FT232H. If you are going to use Python, there's PyFtdi which supports it and that works well (tried it). The FT260S is not officially listed as supported by PyFtdi, so not sure it is.

magic:
There is some limited support in CH341A chips and a Linux kernel driver which makes it work with standard i2c-tools and with in-kernel I2C device drivers.

I have bought a CH341A breakout board from AliE for this purpose, but haven't had the opportunity to try it yet.

I previously used a passive VGA to I2C cable. But this trick doesn't work with DisplayPort anymore and it endangers the GPU if there is magic smoke from your I2C stuff.

Yes, this is my preferred choice now. Before this I used MCP2221A.
