      Righty, i think we are about there with the board.

      https://oshpark.com/projects/tSdupLd4

      Just a spot over $40 for a 3 board trial, so i will keep checking, and i am waiting for some trial boards that should be landing by the weekend, these will let me test soldering the pi direct to the pcb onto SMD pads, and be a final test that you can just wire the screen straight to the pi

        Since when did OSHpark swap the free stickers for free jelly beans? I need to order more often!

        Just need the wait for a few more bits, then I will have news....... If it works.......

          I got my jellybeans with the $3 I spent when I ordered those power breakouts linked on sudomod. You must have gotten premium jelly beans for $40. ;)

            @obsidianspider this is a smaller test project, only $28. It's scary how that price soon shoots up!

              i think i have finalised the board now (i think) just need to find somewhere that can do the boards for less than $40

              the other links probably dont work anymore, but this one will

                China is a good source of boards once you find reasonable shipping (cost/time)

                And when they arrive it's always good

                    That's really cool. How did you manage to solder the Zero's GPIO to the PCB?

                      @obsidianspider well the board has square smd pads which match up with the 40 pins of the zero

                      first step is to tin all the smd pads with a thin layer of solder. gave it a quick coat with a cheepo flux pen from an old solar project, added a spot of kapton tape to make sure the vias dont touch the pi

                      then i clamped the Pi to the PiCB with some m2.5 bolts to hold it steady, pin by pin, hit it with the soldering iron, and push the solder in until the hole is filled, holding the iron on for just a few seconds to make sure the heat has gone though to the pad so everything is joined. repeat 39 more times!!!

                      the screen is the same. tin the pads, scrible on the solder pen, place the screen with some tape to keep it all in place, then touch each pin for a few seconds to melt the solder :)

                        @moosepr So how long until you make a board for a Compute Module 3? ;)

                          @obsidianspider hahaha in not sure on that one. They are a shade more complex! Would be nice though
