README
PCB/README.mdPCB
Welcome to the PCB folder of ChrisBox! The ChrisBox PCB is designed with KiCad. The Project files and generated Exports are found here.
Content of the PCB folder
./exports- The.step-export of the ChrisBox PCB../interactive bom- The interactive HTML BOM (made with Interactive Html Bom). It is useful for handsoldering or just looking up which component has to go where../jlcpcb- Output data from the KiCAD JLCPCB tools. This data can be used for ordering a PCB with components. Always re-check the data yourself!./models- Additional footprints and models, which are not included in KiCad and its plugins itself.
The other files in this folder are the main KiCad project with schematic and pcb, as well as the sub-schematics (ferro_amplifier and usb_connector).
Notes on KiCad settings
The design was made with KiCad 8.0. Installed plugins are the Alternate KiCad Library (by Dawid Cislo), the Interactive Html Bom (by qu1ck) and the KiCAD JLCPCB tools (by Bouni).
Additional Footprints or 3D models are found in the ./models folder.
Always check the JLCPCB options yourself! The tools seemed to "forget" some data from time to time.
Ordering and building the PCB
For ordering instructions refer to ORDERING INSTRUCTIONS. For building instructions refer to BUILDING INSTRUCTIONS.

Questions
How big is the ChrisPCB PCB?
It measures 78 × 46.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ChrisPCB use?
197 parts, built around the AD8605ARTZ-R2, ESP32-S3-MINI-1-N8, LM2775DSG and AP2112K-3.3. 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 ChrisPCB KiCad files?
From the TUDA-MUST/ChrisBox repository on GitHub, at the commit this page was made from: the board is PCB/ChrisPCB.kicad_pcb and its schematic PCB/ChrisPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ChrisPCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask TUDA-MUST before reusing the design.
