Overview
PacSatBaseBoard is an open-source printed circuit board by cminyard, from the cminyard/PacSatBaseBoard repository on GitHub, published under the MIT licence. It is a 6-layer board of 90.2 × 95.9 mm with 41 parts on 123 nets, routed with 73 tracks and 11 vias.
It is built around the ESQ-126-38-G-D, FTSH-105-01-L-DV-K and G125-MH11005L1P, with the HTSW-102-07-G-S among its other parts. Its parts include 12 resistors, 7 connectors, 2 capacitors, 1 diode and 1 inductor.

README
README.mdPacSatBaseBoard
This is a base board design to start with for a PacSat design, or really any Pumpkin Space CSKB board.
To use this, pull this project up in KiCad, then do "Save As" under the file menu and save it in a new directory to use as the starting point for your board. You might have to deal with the .git directory being copied.
All local footprints go into the "footprints" directory, create symbol libraries in the "symbols" directory as necessary. There are already connectors added to those.
NOTE: The CSKB standard has ESQ-126-39-G-D PC104 connectors, which have 12.19mm pins. This leaves around 3mm of pin exposed between the boards. This design has ESQ-126-38-G-D PC104 connectors, which has 7.36mm pins. This leaves the 11.05mm as the board height, and 11.11mm (.438") spacers are pretty common.

Questions
How big is the PacSatBaseBoard PCB?
It measures 90.2 × 95.9 mm and has 6 copper layers, 1.65 mm thick.
What parts does the PacSatBaseBoard use?
41 parts, built around the ESQ-126-38-G-D, FTSH-105-01-L-DV-K, G125-MH11005L1P and HTSW-102-07-G-S. 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 PacSatBaseBoard KiCad files?
From the cminyard/PacSatBaseBoard repository on GitHub, at the commit this page was made from: the board is PacSatBaseBoard.kicad_pcb and its schematic PC104_io_conn.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PacSatBaseBoard 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).
