I start this discussion because there isn't any simple way to have a remote console for the Kflop without using many wires..
So a Konnect board would be a good solution, but the communication over 2 meter it will not work in this conditions.. i wonder if we use two logic level converter (one for each side) https://www.adafruit.com/product/395...FZRj7AodnAUAUw with a higher voltare level (12-24v ), the cross talk and interference will not be a problem any more.
