SMD Connectors for Inter board connections

[kowshik1729]

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.

Manufacturer BOOMELE(Boom Precision Elec)
Mfr.Part # C53390
LCSC Part # C53390

Manufacturer Amphenol ICC
Mfr.Part # 20021121-00020C4LF
LCSC Part # C239061

• Ribbon Cables

• Socket and Plug

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

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.

[salmanfaris]

@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.
