      Second variant with the same board. This one actually sends it's messages better (no more st:fail's):

      IMG_7380.jpg IMG_7383.jpg

      And it's nice and compact. Now I need to find a nice ventilated little box to protect them from dust.

      This board is now tested and shared on OSHPark: https://oshpark.com/shared_projects/unP8BmuI

      Component values are mentioned in the brd file. I will add a BOM in Excel format later.

          This might work - it's well ventilated; width & depth OK, but don't know about height.

                  Preview of my latest board, waiting for prototypes to test this ....
                  topview.png
                  bottomview.png
                  This is a 50x50mm board with multiple powering options (AA or AAA batteries, direct 3.3 or 5V DC, 4.5-20V DC in, 220V AC) and can fit a GSM module at the same time as the NRF24 radio. Allows 2 variants of I2C connection (SDA and SCL on IO header can be swapped via soldering pads). Room for signing chip and some I2C based EEPROM or FRAM memory. Several connectors for digital pins with power.
                  Fits into this box:

                      @GertSanders Hi Gert, on the small board, did you soldered C2 and C3 on the bottom or on top just under/in the IC socket?

                        @pjeterinfo On one of the sensors I soldered it on the bottom between the two connectors on the bottom.

                        For the sensors where I add the batteryholder on the bottom, I do indeed solder these capacitors on topside between the legs of the chip. Later this evening I will make a photo of such a setup.

                            very good job, i'm very interested to try your board. Did you try to order from
                            dirtypcbs.com vs oshpark for the price?

                              I ordered from both. From OSHPark because they have a 10-12 days turnaroundtime for me (to Belgium) so I could test faster and Dirtypcb because of price (quality is as good, only ENIG is missing). The boards are shared on both manufacturers websites.

                              More details here:

                                My AC capable boards have arrived in the mail today, some of these will become repeaters, some will be GSM nodes, I know what to do the coming days :-)

                                  I did also order your red board now and will try it. Do you have a wiring diagram that I can open with adobe reader or something else.

                                    @gloob Here is the diagram: GSRedboard schematic.pdf
                                    This is the same schematic as "selfcontained low power node v1.sch"
                                    Since a Redboard already exists (Sparkfun makes them), I added the GS prefix, but I like the name suggestion :-)

                                      @GertSanders I don't understand the shipping price on dirtypcb. They say "10 each 5x5cm PCBs $14" so that mean that 10 pcbs boards, each are 5x5 cms will cost 14$, right ?
                                      but when I choose buy, I get confused. In the quantity selection there is protpack +-10 which is 14$, and another option to set the quantity to 10, 20 or 30, it increases the price to 28$

                                      Can you please clarify this ? Thanks

                                        http://dirtypcbs.com/about.php

                                        If you need a specific quantity of boards the use a more expensive board house. The proto pack will be 10 +/- 1 boards.

                                          @mountainman Thanks. Strange offer to have expect 9 or 12 boards :D
