🧩 Component Libraries
| Directory | Contents |
|---|---|
| footprints.pretty | 19 custom footprints, including the two logos placed on the board |
| symbols | 7 custom symbol libraries referenced by the schematic |
| 3dmodels | 16 component STEP models referenced by the board |
The component selection follows the PCB component references and its design BOM, with the two board-logo footprints included because they are part of the layout. Unused parts, plugins, caches and backups are excluded. The purchasing BOM is EMON_BOM.xlsx.
🚀 Getting Started
- Install KiCad 8.0 or a compatible newer version with its standard symbol, footprint and 3D-model libraries.
- Open
monitoring-board.kicad_profrom this directory. - The project library tables resolve custom components through
${KIPRJMOD}; no personal library-folder path is required. - Inspect the schematic, board and 3D view before editing or manufacturing.
Standard KiCad components remain linked to the installed libraries. The custom models in 3dmodels/ use project-relative paths. Keep this directory structure intact when copying the project.

Questions
How big is the Monitoring board PCB?
It measures 100 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Monitoring board use?
59 parts, built around the ESP32-DEVKITC-32E, RB-0505D, OP27GSZ and HCPL-7800A-300E. 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 Monitoring board KiCad files?
From the JAJV02002/PV-Monitoring-System repository on GitHub, at the commit this page was made from: the board is hardware/pcb/kicad/monitoring-board.kicad_pcb and its schematic hardware/pcb/kicad/monitoring-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Monitoring board design in my own project?
Its repository states no licence, so its author keeps all rights: ask JAJV02002 before reusing the design.
