Merci Éric !
The MySensors team has done a woderful job. If my tutorial can help a lot of new developpment around MySensors, I will be happy. I've planed the creation of some modules but never had the time to do them. It will come in 2018.
I've used Orcad Capture and Layout Plus for about 20 years; learnt Cadence PCB Designer and Altium Designer; and I've to say that KiCad is a very good CAD : simple to learn and very powerful for a hobbist.
