Questions

How big is the Power sensor hub PCB?

It measures 101 × 84 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Power sensor hub use?

92 parts, built around the ATMEGA32U4-AU, HC-SR04 and SK6812MINI-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 Power sensor hub KiCad files?

From the Roguillo/projects repository on GitHub, at the commit this page was made from: the board is Power_sensor_hub/Board/Board.kicad_pcb and its schematic Power_sensor_hub/Board/Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Power sensor hub design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).

I left this project because it is very expensive. For me these were the numbers: - PCB for JLCPCB would have cost around 52 USD - Plus all the components (not including the keys) around 170 USD - The keys are not that…
