    Hi all,
    many thanks for all the valuable input!
    I will share my files after having tested the board by myself for the first time!

    @GertSanders: I've never thought about using the SMD version of NRF24L01, it really looks interesting!

    @tbowmo: Your board size is really impressive, are you also using the EEPROM and ATSHA on that small size board?

    The smallest and still (hopefully) manufacturable for me seems to be around 44x21mm...

    Right now I'm waiting for all of the parts of my reflow oven, I have some boards for testing here and in case I'm successful with reflowing, I will order new boards in China.

    Best regards,
    Philipp

      @TD22057: My dealer in China does some panelization for me as well, last time I ordered 20 board (size about 25x45mm) and I received 42... That was more than fine for me. But thanks for the link!

        It's complete with external flash (for OTA), atsha204, voltage regulator, 2 led's and a Si7021. Using 0603 smd components though.. (And it only got components on one side..)

        Still working on some details, before publishing it though...

          @tbowmo: Sounds very impressive, chapeau! I'm looking forward to seeing your design when it is finished!

            @tbowmo I have been working on a similar board. The matter of external connections for switches and external sensors keeps me busy. The 1,27 mm spaced headers seem like a possible solution. But I have not found any female headers with wires (Dupont style) to go with the male versions. How do you solve the connection problem ?

              @GertSanders: On aliexpress you can find sets of male and female 1.25mm connectors, do you think about something like that:

                As I read your post again, you mean something like this:

                  @phil83 the micro connector set with the wires is a very good suggestion. I will look around some more.

                    I finally went on with the project and received the pcbs last week... my soldering oven is running and I could finish the first board (still some parts are missing :-( ) If only I had more time to work on that...
                    Here are some impressions:

                    I soldered some cables so that I can program it and check via ftdi...
