I tried it out on mine (a very late version with all R1 spacebar row modifier keys at 1.25x width) - it didn't work, as the software complained "keyboard is not connected", although the PCB is written "KB84" on some Noppoo Choc mini.
Don't want to upgrade to Winkeyless B.mini / Red Scarf III / Duck Octagon just because of these. 'These' being non-standard 5.5x difficult to replace spacebar, not customizable (e.g. HHKB backspace), no macro, no extra layers, no dual usb-bluetooth mode, etc.
Just dag up this post.
I wonder if this also applies to the later versions of Noppoo Choc mini 84 as they are made by the same OEM factory (PLUM).
If yes, it would definitely be great news.
I'd say there's a good chance, but only one way to be sure - someone needs to give it a go!
