Hi there !
I'm waiting for the boards and some components. Then I will be able to test, and write drivers (E931.96, no driver at the moment) and software for the system.
I'm cleaning my files / schematics to release everything.
I wasn't really aware of MYSX connector. After looking the PDF specs, It's not even clear how many pins it has, it look like every new versions add some pins ? It could be considered for a future version.
The thing is I have never worked on an home automation before, nor mysensors. So the idea here was to design a few board that are enough for my basic project needs (RGBW lighting, low voltage halogen lighting, multiple multisensor, Jeedom RPI controller). At the moment I don't really know what flavor of extensions I would one day like to add to the boards so I tried to breakout a maximum of pins, with clear silkscreen, even if it makes the boards bigger. I see this as a dev project to dive into mysensors. Future rev will probably follow if it works for me.
