soldering help needed - one column doesn’t work
basically what the title says. i’ve resoldered the pin, but my OL. column isn’t working. images coming momentarily

If one column isn't working on your keyboard, it's often a hardware issue, typically related to soldering. Here are some steps to troubleshoot the problem:
1. Check the Solder Joint: Ensure that the pin for the non-working column is soldered properly on both the nice!nano side and the PCB side. A poor solder joint can prevent the connection.
2. Inspect for Shorts: Look for any solder bridges between pins or traces that shouldn't be connected. Use a multimeter in continuity mode to check if any pins are unintentionally connected.
3. Identify the Pins: Refer to the schematic for your keyboard to confirm which pin corresponds to the non-working column. This will help you ensure you're checking the right connections.
4. Reflow the Solder: If the solder joint looks good, try reheating the joint to ensure a solid connection. Sometimes, adding a bit more solder can help.
5. Check the Diode: Each switch has a diode that could be causing the issue. Ensure the diode is oriented correctly and soldered properly.
If you've gone through these steps and the column is still not working, it may be best to consult the troubleshooting section of the documentation for further guidance. Good luck!
i’m aware my soldering joints aren’t great, but it’s my first time soldering. i checked the guide and the pin i circled should be the one causing problems. every other key works except that column.
i re-soldered both sides of the pin, but it still doesn’t work. i can’t figure out why.
it doesn’t look like it’s shorted with anything, and the diodes seem fine to me
if you touch the pins manually with tweezers or a wire does it work
touch that pin to 115 for example
i’ll check tmrw, ty for the suggestion, didnt think of that
can i touch it from the bottom?
You can use a multimeter in continuity mode to check everything is connected, following the trace in the pcb along thst column to the microcontroller pin / ground.
yes i would test pins on bottom first as that is what should be connected to your PCB, then if those don't work test on the micro controller
testing on bottom did nothing
testing on top ALSO did nothing
that’s not good
is this a microcontroller issue? i pin issue? a flashing issue?
i can’t tell and i don’t wanna take it apart to find out
are there free pins on the nice!nano? if so, can i write my own firmware to use a different pin for that column?
ya that gpio pin might be dead
you don't have the premium case do you
no why
is it prone to die in the aluminum case*
depends on the environment (if you have a lot of static)
how fixable is this? will i need to buy a new nice!nabo?
i think you can message support about it and they will replace, and there are also free gpio pins
p104 for example
so am i able to change it so that p1.04 is the one receiving input from that column? like writing my own firmware?
@splitdev yes, it's not too bad, first you'd have to bridge the column to a working pin
and then you would define it in the col-gpios
physically bridge it that is
but you might have just been unlucky to have gotten a bad controller I would e-mail them about it and see what they say
