Questions
How big is the Gmeter IHH PCB?
It measures 47 × 36.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Gmeter IHH use?
27 parts, built around the LP2985-33DBV. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Gmeter IHH KiCad files?
From the bernienor/G-meter repository on GitHub, at the commit this page was made from: the board is Gmeter_IHH.kicad_pcb and its schematic Gmeter_IHH.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gmeter IHH design in my own project?
Its repository states no licence, so its author keeps all rights: ask bernienor before reusing the design.

2B is the "definitive" version so all code going forward is designed for that version of the board. Minor hardware differences mean that code for 2.0 may not work on 2.0B without tweaks (mostly related to ram banking)
