Questions
How big is the TempWatchtV1 PCB?
It measures 70 × 35 mm and has 4 copper layers, 1.6 mm thick.
What parts does the TempWatchtV1 use?
65 parts, built around the ESP32-S3-WROOM-1U-N8R2, SN65HVD230D, TPS82130SILR and CP2102N-A02-GQFN28R. 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 TempWatchtV1 KiCad files?
From the steiger-systems/TempWatch repository on GitHub, at the commit this page was made from: the board is Hardware/V1/TempWatchtV1.kicad_pcb and its schematic Hardware/V1/CAN.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TempWatchtV1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask steiger-systems before reusing the design.
