What values are the pull-ups on the Grove Shield for Wio Lite I2C bus?

So the standard mode (100kHz) allows me to use standard 4k7Ω resistors for pull ups on a 2 meter wire IF the premise of the wire having 50pF is real.

What do you think, do I still need to look into IEEE488?

I think you got it no problem.
