The only snag I ran into was the Caps Lock indicator LED. Because there isn't one. Or there kind of can be, but… All the switch LEDs are on the same circuit, powered by the same pin from the controller, for use as backlighting. The one on the Caps Lock switch is just the same, and it can't be toggled separately. To get a Caps Lock LED, I had to only install that one LED and leave all the others out, so I've got no backlighting. That's OK to me, since I didn't give a flip about backlighting, but unfortunately the firmware also has no concept of a Caps Lock indicator, so it doesn't function as one. There's no option in the online configurator for that. So effectively I'll have to go into QMK here on my own computer and hack that function into it and compile it myself. I'm sure I can figure that out, given time, but it's kind of a nuisance as I had been expecting to rely on the oh-so-convenient web-based thing.
Some of you will notice this layout is a minor refinement of the Zo64 that was my first build. I just added one key and dubbed it the Zo65. That new lime-green key is my dedicated Compose key, so I can type all kinds of funky characters (…©™ñ»⅞) with ease. (It actually sends a Scroll Lock signal to my computer, but I configured Ubuntu to read Scroll Lock as Compose.)
I know G20 is low in popularity (to say the least), but I gave it a spin because the split spacebar wouldn't be an issue with it, and I've found I actually like this profile very much. I like having homing bumps on F and J (which DSA and SA can't seem to manage), and the broad key tops and smooth edges are comfortable to me when typing fast.
On the subject of DZ60 versus Banana Split 60… I don't think it's quite accurate to call the DZ60 a “clone” board. The idea is similar, but the execution is very different. So here are some notable differences:
DZ60 has RGB underglow; Banana Split does not.
DZ60 has an individually addressable Caps Lock LED, Banana Split does not.
DZ60 orients the switches with LEDs on the front of every switch, which is the reverse from most boards. As a result, most keycap sets with translucent legends don't work well with it. Banana Split has its backlight LEDs on the backs of the switches, which is more normal.
Each board supports some layouts that the other does not. Banana Split Round 2 has more bottom-row options, while DZ60 allows the funky fourth-row offset.
Banana Split 60 has a physical reset button to use when flashing the controller. DZ60 Round 2 with the USB-C option does not, relying instead on some awkward and easily-forgotten combination of keys held down when powering it up.
Oddly, Banana Split uses smaller SMT components, including an Atmel MEGA32U4-MU versus the DZ60's MEGA32U4-AU. They're the same chip, only in a different package.
