These are the board files for the first revision of the thermocouple board for ALI. As can be seen in the schematic, the layout for the ethernet PHY is wrong. This was corrected with some jumper wires and hot glue. Because of the very similar architecture to the new layout, this board may be used in lieu of the completion of a second revision of the original thermocouple board.

Questions
How big is the Ground station pressure transducers-1A PCB?
It measures 67 × 68 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Ground station pressure transducers-1A use?
110 parts, built around the LAN8742A-CZ, TJA1042T/3/1J, AP2112K-3.3 and USBLC6-2SC6. 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 Ground station pressure transducers-1A KiCad files?
From the npgo22/ALI2Proposal repository on GitHub, at the commit this page was made from: the board is ground-station-pressure-transducers-1A/PT.kicad_pcb and its schematic chickenstick-locator-1A/Power.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ground station pressure transducers-1A design in my own project?
Its repository states no licence, so its author keeps all rights: ask npgo22 before reusing the design.
