README
Hardware/Control Board/README.mdControl Board
This folder contains details of the EUCLID+ Control Board.
[This is actually a photo of the v1 Control Board. This earlier version had a different slightly footprint for C8, which is now a radial electrolytic. Also, some of the PCB tracks carrying power on the v2 version are thicker than on the V1 version, which is archived in the v1 Control Board folder]
The populated (v1) Control Board is seen (from the top/component side) in the photo below. It is mounted to the Front Panel by the two (9mm Alpha) potentiometers and the ten ("Thonkiconn") sockets mounted on the bottom side.
Also visible in the image above are the two 1*18 0.1 inch headers which join the Main and Control boards electrically. These are female headers on the top of the Control Board, which mate with corresponding male headers on the bottom of the Main Board. These headers provide sufficient mechanical mounting of the two boards for 'static' applications, but there are provided two 3mm clearance mounting holes, H1 & H2, to make a more robust assembly with M3 screws and spacers, if required.
This folder contains a KiCad Project File (.pro), a Schematic File (.sch) and a PCB file (.pcb).
There is also a BoM, which is an Excel file; you will have to download the raw file and view it outside github.
A version of the schematic in graphical (svg) format is available in the Operation folder

Questions
How big is the Euclid+ Main Board PCB?
It measures 78 × 108 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Euclid+ Main Board use?
131 parts, built around the TL084, BC546 and BC556. 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 Euclid+ Main Board KiCad files?
From the m0xpd/EUCLIDplus repository on GitHub, at the commit this page was made from: the board is Hardware/Main Board/Euclid+ Main Board.kicad_pcb and its schematic Hardware/Control Board/Euclid+ Control Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Euclid+ Main Board design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
