Questions
How big is the Tesseract PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tesseract use?
89 parts, built around the ESP-12F, LM2596S-5.0, AMS1117-3.3 and 1N5819WS. 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 Tesseract KiCad files?
From the IoTCloudStudio/HW_Develop repository on GitHub, at the commit this page was made from: the board is Productivo/Tesseract/PCB/Tesseract/Tesseract.kicad_pcb and its schematic Productivo/Cloud UPS/V2/UPSV2concepttocheck.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tesseract design in my own project?
Its repository states no licence, so its author keeps all rights: ask IoTCloudStudio before reusing the design.
