Finally i have them in my Hands. The new revision of the protothing. As the last revision also ordered at DirtyPCB's the 50x50mm PCB Protopack - got 11 of the +/-10 boards they say. I really love the fact that i do not need to pay extra for the black soldermask that is maybe not always the best choice but for a c-base board needed. The print is on the top is a tiny bit off but nothing bad. Will order again.
The first thing i try is to create a small Arduino clone with regulated 5 V just to see how good the idea with the power section at the bottom works.
And as the last batch, i will also spread them to c-base members to see what they will come up with. Maybe if all the other that will get a board say this is good i will order a bigger batch.
