Ergonomic, split and other weird keyboards

Rules

Keep it ergo

Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)

i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²

¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid

Hey all.

I am currently prototyping a keyboard with the Seeedstudio Xiao BLE (nrf52840). I configured the shield config correctly & got it working. However, my RGB won’t turn on (followed the ZMK documentation on RGB underglow)

Does anybody have a pointer to a project that got RGB working with Seeedstudio Xiao BLE & RGB?

Are you feeding the leds with 5v or 3.3v? I've had issues with 5v and no shift registers as the led won't pickup the high state of the leddata without a shift register.

https://github.com/WainingForests/zmk-config-xiao/tree/Xiao_rgb I have successfully done LEDS just fine. Per key is a misnomer though. ZMK doesn't allow individually addressing each key. Instead, you'll be using underglow to apply effects to the whole "chain."
