README
README.mdGetting Started with Create React App
This project was bootstrapped with Create React App.
Available Scripts
In the project directory, you can run:
npm start
Runs the app in the development mode.
Open http://localhost:3000 to view it in your browser.
The page will reload when you make changes.
You may also see any lint errors in the console.
npm test
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
npm run build
Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
npm run eject
Note: this is a one-way operation. Once you eject, you can't go back!
If you aren't satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.
You don't have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.

Questions
How big is the PicoCam DowlingZachary PCB?
It measures 50.8 × 44.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PicoCam DowlingZachary use?
55 parts, built around the RP2040, W25Q128JVSIQ, MCP73831T-2ACI/OT-HXY and SN74LVC1GU04DBV. 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 PicoCam DowlingZachary KiCad files?
From the dowlingwong/my_notes repository on GitHub, at the commit this page was made from: the board is public/pcio_cam/PicoCam_DowlingZachary/PicoCam_DowlingZachary/PicoCam_DowlingZachary.kicad_pcb and its schematic public/pcio_cam/PicoCam_DowlingZachary/PicoCam_DowlingZachary/PicoCam_DowlingZachary.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PicoCam DowlingZachary design in my own project?
Its repository states no licence, so its author keeps all rights: ask dowlingwong before reusing the design.
