Jamesdonkey R2 V2 vs R4: your questions
The core difference is the layout size. The R2 V2 is a 96% keyboard that includes a numpad and dedicated navigation keys, while the R4 is a more compact 75% layout that omits the numpad and function row to save space. The R4 also advertises multi-structure compatibility and includes a volume knob.
Yes. Both the Jamesdonkey R2 V2 and R4 feature full-key hot-swappable sockets according to their specifications and vendor descriptions. This allows you to easily change the mechanical switches without soldering.
