README.mdLumenPnP Feeders
The LumenPnP Feeders are open source pick and place feeders to aid in Mid-Scale Manufacturing.
LumenPnP Feeders are available for sale on the Opulo Website. If you build or buy one, please help the project by documenting bugs with a GitHub issue.
The LumenPnP Feeders run Photon, an open source firmware project for pick and place feeders. The popular pick and place control software OpenPnP has Photon support built in, so it's easy to get going with the LumenPnP feeders using your existing OpenPnP setup. These feeders are designed to work with the LumenPnP.
The development process is being cataloged in a series of videos. A playlist of these can be found here.
Documentation
Feeder user documentation can be found on the Opulo Docs Page. Open Hardware Assembly instructions can be found at ohai.opulo.io.

Questions
How big is the Interposer PCB?
It measures 10.1 × 9.8 mm and has 2 copper layers, 0.39 mm thick.
What parts does the Interposer use?
11 parts, built around the MAX3078EIN. 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 Interposer KiCad files?
From the opulo-inc/feeder repository on GitHub, at the commit this page was made from: the board is pcb/interposer/interposer.kicad_pcb and its schematic pcb/interposer/interposer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Interposer design in my own project?
Its repository states no licence, so its author keeps all rights: ask opulo-inc before reusing the design.
