From the project
Source for LumenPnP Feeders
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.
