Thanks @Ludo for the instructions.
Here is the final result, 2 72 studs long MILS modules, each with a PU Hub, a L motor and a color/distance sensor. Everything will be controlled with BAP.
@michaelgale Are there any news concerning the release of R120 / R136 / R152 ?
Ordered!!
But I made a big error. I wanted to order 2 boxes with left and right switches, and finally ordered 2 boxes of 2 x right.....
So I had to reorder 4 left switches.... Anyway I will need them...
