Some comments on using the VIA app with a Mac computer and the Gentoo...
I have an M1 Mac Studio with MacOS Ventura 13.1. VIA is offered as an online app and as a downloadable desktop app. If you use the Safari browser, as I do, you have to install the desktop app.
The Arm-based STM32 microcontrollers on the two versions of the printed circuit board, solder and hot-swap, are apparently pre-flashed with the Gentoo firmware and work with VIA out of the box. No need to use QMT Toolbox.
Be sure to use a USB-C data cable, not just a USB-C power cable, to connect the PCB to your computer.
The first screen capture below shows the VIA Configure page. I connected the hot swap PCB to my Mac and VIA recognized the PCB immediately (red arrow).
The second capture shows the VIA Key Tester being used to test, before assembling the keyboard, whether all of the electrical connections on the PCB are working. Turn on "Test Matrix" (bottom of the screen capture). I used a paper clip, after burning off a bit of the paper clip's plastic coating at each end, to make the connections. Tweezers are less fiddly, but mine weren't handy. All of the keys changed colour from grey to pink, meaning that I could go ahead and assemble the keyboard. I have both versions of the PCB and tested both at the same time. If there's a problem with one of the PCBs I want to know that now, not down the road when the PCBs are no longer available.
