hardware/mss/schematics/Arduino Uno Hat/README.mdOQM MSS Arduino Uno Hat
This is a Kicad project to create the PCB for the MSS Module controller hat for the Arduino Uno.
Steps after updating
Steps after updating schematics/pcb:
- Write out BOM
- Schematic View
- Tools -> Generate Bill of Materials
- Select
outputs/OQM MSS Arduino Hat BOM.csv - Hit Export
- Update PCB
- PCB View
- Hit Update PCB from schematic (F8)
- Fill all zones (Edit -> Fill All Zones) (B)
- New Image
- PCB View
- 3D-Viewer (alt-3)
- Setup nice, squareish image
- Enable raytracing
- File -> export current fiew as JPEG, saving to outputs folder
Get outputs for fabrication
- Put outputs in
outputs/fab/ - For upload to PCBway, put all files in fab dir into a zip file.

Questions
How big is the Arduino Uno Hat PCB?
It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Arduino Uno Hat use?
17 parts. 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 Arduino Uno Hat KiCad files?
From the Epic-Breakfast-Productions/OpenQuarterMaster repository on GitHub, at the commit this page was made from: the board is hardware/mss/schematics/Arduino Uno Hat/Arduino Uno Hat.kicad_pcb and its schematic hardware/mss/schematics/Arduino Uno Hat/Arduino Uno Hat.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Arduino Uno Hat 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).
