It seems that I've got another board: it have 4 holes above GND, D2, D3 and D4, and DI00 is connected to the one for D4.
Is this an old version?
I've ordered at the beginning of this year.
According to this connection guide https://www.mysensors.org/build/connect_radio the pro mini D2 will connect to RFN69's DI00.
But the shield seems to connect D4 to DI00.
Is it OK? Or we need to adapt our sketches?
Excellent, it worked
