Try Onshape, very simple and free.

@scalz: good tip! I prefer to triple check before committing to a pcbmaker.

@jesper I knew that vera can work with many ethernet gateway but this ability is a subject of the Mysensors plugin, not a subject of the gateway We need to call someone who is aware of the abilities of the Domotics and MQTT plugins

@jesper said: the 433 Mhz sensor can range where nRF24L01 can not. What do you mean by "range"? Regarding memory, a Due would have enough memory to do both.
