Today, I ordered version 1.0.1 of the board from OSH Park.

With this version, I fixed the pin assignment of the radio chip, added pin 1 indicators for the MCU and the radio chip, and added more ground plane copper on the top layer.

It will probably take more than a month until I get the boards delivered, but I am really looking forward to playing with them.

@oshpark Thanks! Yes, this design is using your 2 layer service with 2oz copper. The antenna gain is better with more copper. I also quite like to put the SWD connector across the edge and the thinner board that you offer with the 2oz service turns out to be a perfect match for the 0.05" pitch connector.

  Are you sure? yes | no

@Hannes Hochreiner Nice layout!  Is it designed for our 2 layer service with 2oz copper?
