README
README.mdLumenPnP
The LumenPnP is an open source pick and place machine that reliably and accurately assembles electronic components onto circuit boards.
The LumenPnP is available for sale on the Opulo Website. Machines are being used in active production daily. If you build or buy one, please help the project by documenting bugs with a GitHub issue.
Please read the wiki here! The wiki covers information about the state of the project, contributing instructions, and frequently asked questions.
Along with the pick and place machine itself, the project also includes feeders designed to work with the machine. The source for powered feeders can be found in their separate repository.
For exported versions of the source (STLs, schematic PDFs, compiled binaries, etc), you can find them attached to the latest release.
The LumenPnP's development process is being cataloged in a series of videos. A playlist of these can be found here.
How do I get one?
You can buy a machine on the Opulo Website!

Questions
How big is the Mobo PCB?
It measures 149 × 95 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Mobo use?
399 parts, built around the TMC2226-SA-T, PESD3V3S2UT, FDS4435BZ and PESD5V2S2UT. 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 Mobo KiCad files?
From the opulo-inc/lumenpnp repository on GitHub, at the commit this page was made from: the board is src/PCB/mobo/mobo.kicad_pcb and its schematic src/PCB/blade12/blade12.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mobo design in my own project?
Its repository states no licence, so its author keeps all rights: ask opulo-inc before reusing the design.
