Open ARM9 SBC

Powerful Devices in small sizes are possible with ARM based devices. Handhelds, Netbooks, Robots and Small Machinery can integrate an ARM based SBC with Touchscreen at moderate cost and low energy burden.

If you want to scale higher in some dedicated embedded solution for a specific need, you also need the full power of a PC, Then an ARM based system with Linux OS, can be Tailored to a perfect fit.

Open ARM9 SBC

This page documents an ARM9 single board computer designed for image acquisition and processing. It's an open implementation, which means schematics and layout files are freely available. The platform runs Linux/ARM.

Kicad EDA - Design a Product

Kicad is an open source (GPL) software for the creation of electronic schematic diagrams and printed circuit board artwork.

KiCad EDA Software Suite

Designed and written by Jean-Pierre Charras, a researcher at LIS (Laboratoire des Images et des Signaux) and a teacher in IUT de Saint Martin d'Hères.(France), in the field of electrical engineering and image processing.

KiCad Schematic

The electrical rules check (ERC) automatically verifies your schematic connections. It checks for output pin conflicts, missing drivers and unconnected pins.

KiCad comes bundled with a vast library of symbols, footprints, and matching 3D models. They are community maintained so they never stop improving.

Make professional PCB layouts with up to 32 copper layers. This modern tool will help you lay out your board faster. As you draw your track, it pushes forward traces that are in the way. If that is not possible, your track will be rerouted around obstacles.

KiCad PCB

KiCad consists of ..
  • kicad - the project manager
  • eeschema - the schematic editor.
  • cvpcb - the footprint selector for components used in the circuit design.
  • pcbnew - the PCB layout program.
  • gerbview - the Gerber (photoplotter documents) viewer
