The PanelOne is a simple LCD, rotary encoder and SD card board designed initially for RAMPS but adapter boards may be produced for other electronics
Version 1 Design requirements:
- Single sided PCB that could be routed/silk screened easily - Use cheaply available, through hole components - Use cheaply available, pre made cables
Subsequently version 2 has been released which uses some surface mount components but still plugs into a RAMPS with cheap 2x5 IDC cables which are readily available, with no adaptor board required. More info on this blog post which also covers a further update that makes the same design compatible with either 3.3V or 5V electronics.
As always Think3dPrint3d designs are open hardware (CERN OHL 1.2) - the latest KiCAD files are available on our Github.
