Max I2C USB Cable Length?

Post by Zexston »

Hello all,

I am wondering what the max length of the I2C USB cables that are used for the expansions?

I2C states max length at 9-12 feet. I'll be needing to push that with my sump in the basement.

Also - what chips are used in the expansion hub?

I've seen people stretching that far without a problem.
Chip is PCA9518
