Questions
How big is the UPSV2concepttocheck PCB?
It measures 135.3 × 51 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UPSV2concepttocheck use?
66 parts, built around the ESP32-C3-DEVKITM-1, NE555, BC548 and BC557. 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 UPSV2concepttocheck KiCad files?
From the IoTCloudStudio/HW_Develop repository on GitHub, at the commit this page was made from: the board is Productivo/Cloud UPS/V2/UPSV2concepttocheck.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 UPSV2concepttocheck design in my own project?
Its repository states no licence, so its author keeps all rights: ask IoTCloudStudio before reusing the design.
