Multiple Keys give "Enter" as input

[cold ingot]

Recived my Two HE yesterday and just now pluged it.
Already while navigation to wootility.io I felt something was off.

Multiple keys dont work as they supposed to be from what i have tested by now "backspace", "´", "+", "#", "R-Shift","arrow left", "arrow down", "f12", "f11" all sends the input "enter"
Assigning a normal letter to the keys in wootility sometimes let them trigger an double action aka sending the "letter" + "enter".

While writing this I noticed that the keys that send "enter" dont have the full 4mm - smth. between 0,9 to 1,3mm.

I'm pretty clueless / help pls?

Did you try disconnecting it and reconnecting it and wait 5 seconds without touching anything? Maybe the keyboard didn't calibrate properly.

[cold ingot]

Yes startet with that, reset all keyboard settings on wootility and also did a factory reset on wootility all with no succes

Can you show us what you see in this website? when you press those keys?

press one of the keys a few times and send a screenshot

uhm i guess this show all the input the keyboard sends? - if so there is more than the problem i have :/

[violet canopy]

So you got all of that from pressing only 1 key?

[cold ingot]

without pressing anything

i removed all key caps thought smth was stuck or so but still same

Sorry to ping you @timber monolith but maybe this is related to what you mentioned last time here?

It seems that all that set of keys are constantly triggered so I wonder if it's the opposite issue where all of them work instead 😅

I would open a support ticket @cold ingot I never saw this kind of error 😅

[cold ingot]

sure thing will do, just wanted to double check if there was an easy fix :)

[timber monolith]

ugh... so the issue at hand doesn't look good as it appears that the keys affected are all on one component, the "U5" multiplexer or mux
image for references.

so normally when this happens the component is shorted most of the time from a spill but as you mention it arrived in this way i think the component was not properly soldered and in transit a connection was broken disconnecting the mux

this would be warranty replacement situation

if interested the keyboard microcontroller doesn't have enough inputs/pins to read 108 sensors so we use a multiplexer or mux instead to input 14–16 analog values from the hall sensors and output to a single line it rotates between each input rapidly

the image above is what multiplexer each one is connected to
