README
README.mdelectronics
A personal collection of electronics projects, experiments, and reusable design assets.
This repository includes circuit designs (mostly KiCad), component libraries, simulation files, prototypes, firmware/code, and supporting documentation. It is organized as a working archive where each project can include one or more of the following:
- Hardware design files (schematics and PCB layouts)
- Build/manufacturing outputs (for example gerbers)
- Notes, references, and datasheets
- Source code or firmware when the project includes programmable parts
Folder Structure
Top-level folders are grouped by purpose. Common locations include:
circuits/: Main project folders for KiCad designs (schematics/PCBs).doc/: Documentation, references, datasheets, books, project notes, and how-to material.src/: Source code and firmware-related project code when applicable.3d/: 3D models (for example STEP files) used for PCB/mechanical integration.symbols/: KiCad symbol libraries.footprints/: KiCad footprint libraries.gerber/: Generated manufacturing outputs for selected projects.spices/: SPICE/LTspice simulation files.prototype/: Early-stage prototypes and exploratory files.projects/: Additional project work that may not fit the maincircuits/layout.media/: Images and other media assets.pcb/: Standalone PCB-related utilities or adapter boards.tools/: Tooling and utility resources.repares/: Repair-related project material.tmp/: Temporary files.
Project Organization Notes
Project contents are not always in a single folder. Depending on the project stage and history:
- KiCad circuit files are often located under
circuits/<project-name>/. - Documentation can be stored separately under
doc/. - Code or firmware is sometimes placed under
src/.
This split keeps hardware design, documentation, and software concerns organized while still allowing each project to evolve over time.

Questions
How big is the Esp32htv0 PCB?
It measures 60.5 × 84.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32htv0 use?
36 parts, built around the ESP32-WROOM-32UE-N4 and BME280. 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 Esp32htv0 KiCad files?
From the orri93/electronics repository on GitHub, at the commit this page was made from: the board is circuits/esp32htv0/esp32htv0.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32htv0 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).
