About Treadstone48
The Treadstone48 is 47 or 48-key (50%) Symmetric staggered keyboard. It is based on the Rhymestone. Therefore, The Rhymestone can connect to the Treadstone48 as Numpad or lefthand keyboard. (rev1 only)
This Symmetrical Staggered is designed to be easy to use in a natural posture and easy for your fingers to reach.
And more one topic, this key arrangement can use general ansi 104 keycaps.

About Treadstone32
The Treadstone32 is 32-key (30%) Symmetric staggered keyboard. It is based on the Treadstone48 and the Stonehenge30.
This keyboard is removing dedicated modifire-key from the Treadstone48 for more compact. But 2 thumb-key is left same as Treadtone48.

Questions
How big is the Treadstone32 PCB?
It measures 198.8 × 75.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Treadstone32 use?
85 parts, built around the ATMEGA32U4. 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 Treadstone32 KiCad files?
From the marksard/Keyboards repository on GitHub, at the commit this page was made from: the board is treadstone32/pcb/rev1.1/Treadstone32.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Treadstone32 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
