      Hi guys,

      Hope every one are doing well . I'm in need of suggestions for SMD board to board connectors. I'm not able to wrap my head around different connectors available out there.
      I'm having a ring something like as shown below. The blocks colored in red, pink, blue and dark pink are the connectors. I would like to get your suggestions on what kind of SMD connectors best suites my project.

      1. The connector must not be too high.

      2. They must be easy to interface with other rings same like these through wires.

      Suggestions are much appreciated.

        Hi @kowshik1729, There are several methods you can check. I can list some.

        • Male and female smd header pins: You can use smd female and male headers to connect two boards.

          @salmanfaris I'm looking for something very small and with less pin count(probably 4). Something like as shown below.

          0087b41e-d951-44d8-a8e5-0c36e0026551-image.png

          but I need a connecting wire that correctly fits these connectors. So, Can you suggest me a receptacle and wire pair?

            @kowshik1729 But you need to stack the PCB on top another right?

            If you need these type connector you can check Seeed Grove connector with grove cable or Sparkfun Qwiic with Qwiic cable

              @salmanfaris No, I will not stack the PCBs on top of each other. I'll be daisy-chaining them, I guess the second picture which you kept is good but are those connectors SMD?

              I need strictly SMD.

                @kowshik1729 If you need to stack the PCB, then check the first comment I made all of them are SMD

                @kowshik1729 said in SMD Connectors for Inter board connections:

                Something like as shown below.

                In the second comment you shown JST connector and that's a horizontal connector, you can't stack PCB vertically with that.

                  @salmanfaris Great. Can I know the manufacturer part number please? It would be easy for me to take my design to production easily.😊

                    @kowshik1729 Sure, I already mentioned that in the post itself, please check.

                      @kowshik1729 The Sparkfun Qwiic Connector Libray can be found in the Sparkfun Eagle library under SparkFun-Connectors.lbr->Qwiic Connector.

                        I'm an Oral-Maxillofacial Surgeon working with a trauma hospital and academic setup in Delhi. We get our 3D models, from Curewith3D, a dedicated 3D lab equipped with FDM and SLA 3D printers, focused on presurgical planning and patient-specific modeling.

                        We routinely use 3D printed anatomical models, especially for complex facial reconstructions, TMJ cases, and orthognathic surgeries. They’re invaluable for surgical rehearsals, resident training, and most importantly, patient education. When patients can physically hold their jaw model and understand the procedure, consent becomes more informed and anxiety levels drop.

                        As for printing surgical instruments or implants, we’re cautious. While the 3D orthopedic implants we design are precise and patient-specific, their final manufacturing still goes through standard biocompatible grade processes. Like in most regions, concerns about sterilization, structural integrity, and litigation prevent experimental tools from entering the OR directly. That said, the potential for custom joint replacement implants and 3D knee replacement implants in underserved areas is enormous. We see 3D printing as a huge enabler in low-resource and humanitarian settings.

                        Signal Hunt: An ESP-NOW Workshop & Treasure Hunt

                        Hello everyone! We’re planning on organizing a two-phase event that explores device-to-device communication using ESP-NOW protocol :

                        Workshop: Participants learn to build and program ESP32-based receivers with a web interface that directly exchange signal data using ESP-NOW for RSSI-based distance approximation.

                        Signal Hunt Competition: Equipped with these receivers, participants will track hidden ESP32 transmitters scattered around the campus, each with distinct point values.

                        Current hardware setup:
                        Reciever(one per team):
                        Esp32 ~ 360rs
                        9v battery = 20rs
                        9v battery clip= 5rs
                        buck converter (MP1584 or LM2596) ~ 45rs
                        Perfboard + male to female berg strip ~30rs
                        Total per reciever ~ 460rs
                        Transmitters :6
                        Components same as recievers = 460*6~2760rs

                        (using non-rechargeable batteries to reduce cost,
                        will using a 7805 voltage regulator IC be a viable way to reduce cost further?)

                        We’d love your suggestions on ways to simplify hardware, reducing the cost, secure partnerships and funding, or enhance the interactive elements. Thank you, looking forward to any ideas that can help make the event engaging and successful!

                        So today, I was reading about a kid who got a custom prosthetic arm printed like really. Holly molly! People are printing prosthetics nowadays! That’s when I stumbled upon Curewith3D, and wow, 3D printing in healthcare is on another level.

                        Apparently, I found out that they’re not just 3d printing limbs. They actually use patient-specific scans (like CT/MRI data) and some DICOM files to design prosthetics that fit the person’s body perfectly. Every angle, curve, and dimension is matched to the individual. No more bulky or uncomfortable fits.

                        What’s wild is how fast and affordable the process is. Instead of traditional molds and weeks of waiting, Curewith3D can design, print, and deliver a customized prosthetic in a fraction of the time.

                        I didn’t know 3D printing services could be this life-changing, and it's happening right here in India. It really makes you wonder what else we’re going to be printing next.

                        Anyone else heard of this or know someone who’s used a 3D printed prosthetic? Would love to hear more.

                        I am trying to set up a janus webrtc to stream an RTSP to an HTML page.
                        I have followed the getting-started steps by Janus-gateway official github repo.

                        Since I am new to web development. I do not understand how to host the Webrtc server. can anyone guide me to set up an HTML page that can display a video stream from an RTSP server using janus webrtc?
