Questions

How big is the OpenHardwareHolterMonitor PCB?

It measures 131 × 80 mm and has 6 copper layers, 1.6 mm thick.

What parts does the OpenHardwareHolterMonitor use?

165 parts, built around the ESP-WROOM-32D, MCP73833, TPS2113APW and DMG2305UX. 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 OpenHardwareHolterMonitor KiCad files?

From the OpenElectronicsLab/OpenHardwareHolterMonitor repository on GitHub, at the commit this page was made from: the board is kicad-files/OpenHardwareHolterMonitor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the OpenHardwareHolterMonitor design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
