dasbob's Issues

Plate for hotswap

Really like the design and tempted to order a set of PCBs, just curious if you wanna make it hotswappable, don't you need a plate to keep the switches in place?

Traces shorting 3a and 7a/DNUOS

Thanks for sharing your design! Looking forward to using it. Let me preface this by saying that this is the first time I've had open-source PCBs made, so I'm certainly not ruling out error on my part.

I had these made by JLCPCB and, for whatever reason, I'm having issues with certain pins across all 5 PCBs. Given the consistency of the issue, I'm wondering if two or more traces are too close together. Specifically, I'm having issues with traces 3a and 7a/DNUOS (I'm using a nice!nano v2). Using an ohmmeter, I can bridge the two corresponding pins.

I may try digging out the traces and hand wiring since it only seems to be the two switches which are impacted.

key rollover

Hello!
That's not an issue, it's more a request to provide more information about the key rollover.
Being diodeless, I assume DASBOB must have some limitations due to ghosting, but I was not able to find any information about that.
The layout I would like to use has some combinations with 3 keys on one part and 2 on the other one.

Thank you!

Are the labels for the buzzer on the PCB backward?

Thank you for this creating and releasing this PCB. The thumb clusters located excellently for my hands. I could not help but add a piezo buzzer for the fun of it and oriented the "+" label of the buzzer with the "+" labeled on the PCB--the right pad. The buzzers made no sound until I reversed the orientation. Is the PCB mislabeled?

Also, the right side does not work with audio enabled and both halves are connected. Does a AUDIO_PIN_ALT need to be defined? Do you think that may be the root cause of my issue?

Thanks again for a great layout and PCB design.

"+" on Buzzer appears to go to the "+" printed on the PCB:

Firmware for ZMK

I am really interested to Build this Keeb. It would be great if you can make ZMK firmware since I use wireless keeb. Can you please make a ZMK firmware for this keeb?

Created KMK firmware file for DASBOB36

Thank you for the board design. I have made it function using the KMK firmware. Just wanted to say thanks and also give you this link if it may be of interest/value to you.
