Questions

How big is the SenseEHajo PCB?

It measures 141 × 56.9 mm and has 2 copper layers, 1.6 mm thick.

What parts does the SenseEHajo use?

104 parts, built around the 74LVC1G125, ESP32-WROOM-32, HLK-PM01 and MCP3221A5-E. 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 SenseEHajo KiCad files?

From the calm4git/SenseHaJo-ESP32 repository on GitHub, at the commit this page was made from: the board is SenseEHajo/SenseEHajo.kicad_pcb and its schematic SenseEHajo/SenseEHajo.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the SenseEHajo design in my own project?

Its repository states no licence, so its author keeps all rights: ask calm4git before reusing the design.
