Having trouble finding i2C cables (Stemma/Qwiic/QT) shorter than say 5cm. Also no luck finding a crimp tool kit to make my own, also screened/twisted pair i2C cables. Located in or shipping to UK needed.….
I am hoping you mean Qwiic/STEMMA QT cables?

Yes, post updated and meant to say shorter than 5cm….
Ha ha, changing the rules of the game, eh?
I have not seen cables shorter than 5cm. BTW, the Pi Hut was my goto on-line store when I lived in the UK.

This may cause (additional) problems because the SDA and SCL line do not have differential drivers.
FYI I have my ZT-703S digital oscilloscope connected to the I2C bus running at 400Khz with 3x20cm=60cm (dupont) jumper wires/BNC screw connector and I do not see any problems with the signals. I did a comparison using SCL with jumper wires on channel 1 and a probe on channel 2 and they looked identical.
