The cable/connector does indeed look interesting, if easily available ... possibly with more pins... I wish they had more details, from the thumbnail[0] they posted of the board edge PCB footprint, I don't see how it could be reversible... The short finger (presumably VDD) would need to be on opposing sides top and bottom, and it's always on the right. Or is my thinking messed up?
The original jackplug was also just as simple. Instead of 3.5 they could have gone for the 2.5" to avoid confusion as an audio out. But the new proposed cable? Is it available? Seems to be more work to offer.

Nope, still not.
Kittenbot devices came with a standard audio jackplug. Easy cabling, off the shelf.
Although, thinking about it, I wonder if the connector is designed for sequencing (power/ground first, then data) and if the linear insertion of the jack plug caused issues with that, since when the plug is being inserted the connector nearest to the outside contacts all three of the rings on the jack in turn.
