Hi,

config.txt only effects RPi boards. We leave this in for all images, simplifies coding, as we don't require if checks on file locations each time we want to modify a shared item across multiple devices.

As for i2c frequency and changing this, no idea, sorry.
If you find our project or support useful, then we’d really appreciate it if you’d consider contributing to the project however you can.

Would be good to find out as it is stuck at 100k - no reason not to go to 400k if we knew how
