Currently there are two versions of the hardware, one is a veroboard prototype [V1] which i use for initial software development and concept testing. However I now feel comfortable that it will work so i have started developing a new version of the hardware [V2]. The design of the [V2] schematic is now "completed" and the work on the PCB is fully routed, some finishing touches to the silkscreen is needed before it will be sent for to production.
The KiCAD files for the [V2] board are available in the svn repository under trunk/sch/v2
