- I've decided to go PRO with my cable connectors in the future. You'll see why.
► PCBWay $5 for 10 pieces www.pcbway.com
So a recent project started to fail due to a bad decision on which connectors to use. I've made a jump to some industry standard ones now.
► JST Plugs, sockets, with/out flying leads (wires)
Right angled PCB sockets (good for board edges): s.click.aliexpress.com/e/_AryKgT
Plugs & sockets pre-wired, various ways: s.click.aliexpress.com/e/_Ap1q43
2-pin male plugs :www.banggood.com/custlink/GvK...
2-pin female sockets: www.banggood.com/custlink/DKG...
► IDC connectors
Plugs like the ones I show: s.click.aliexpress.com/e/_9gUW3D
Premade cables, various ways: www.aliexpress.com/item/33029...
Bare cables (fit your own plugs): www.aliexpress.com/item/32998...
IDC cable for Arduino use (prewired): www.banggood.com/custlink/Gmm...
► IDC Crimping Tool
Selection of crimps plus the tool: amzn.to/3LUmGxX
Just the crimper: amzn.to/3Iqby9N
Take a look around, lots of very similar tools, varying prices

Excellent video - thank you. I'm having the same problem with Dupont connectors which are still desirable due to their compact design (could be improved with more robust contact elements in my opinion). I have however had some success by lightly tinning the faces of the pins - very quick and easy and makes a huge difference to holding the connectors on.
Wait, Are you using single pin dupont connectors like you show with the Arduino? If so, there's your problem!
The secret to reliable dupont connectors is to not use individual connectors. If you have a 4x1 row of 2.54mm pin headers, use a 4x1 dupont connector instead of four individual connectors. Then the required force to remove the cable is much higher. It basically becomes the same as IDC. You can also key the multi gang dupont connectors using plugs and a corresponding missing pin on your header.
dupont lets you plug the connector the wrong way. that's a big no no
You mention in the video, that you recommend putting on the strain relief for the IDC connector. I have found, that these connectors are sold both with or without the stain relief. The regular connector with strain relief is used most. However there exists male connectors for the PCB that has clamps on, that go over the female connector after it is seated. This connector with clamps works without the strain relief on the female connector. There os not room for both strain relief and clamps. You have to pick one.
Fun tip, you can really use just about any connector if you put a dab of hot glue on.
Great video. I've been using Dupont connectors in my prototyping for a long time now and I find that they are very good as long as the parts aren't subjected to movement. Another good solution is latching 2.54 connectors (Molex clones), which are typically used on PC fans. They provide a durable keyed connection and as an added bonus they can handle up to 4 amps per pin (if you're brave!). Best of all, you can get the headers in 90-degree flavour so your connector sits flush with your PCB, which is great for low profile builds.
Very helpful. Thanks. Be good to talk with you. richp-tech
Are you sure that those JST connectors are exactly 2.54mm pin spacing?
Those IDC cables are pain in the ass' had to replace loads of those on Marshall Amp's because the spikes were in poor contact for siganals from the pre amp/Eq to the power stages caused all sorts of shit , used to make up JST cables to replace ..............
Very good point albeit one that honestly shouldn't have been needed, but definitely was 😁
Jeez, just get to the point of why I clicked this!!
A chinese 3D printer accessory manufacturer ships their touch screen with dupont plugs, because they have
when i mount something on the board itself then i use dupond. External Power is via Pluggable Screw terminal from phoenix contacts or dc barrel jack
oh i have once tried to press together a 24 wire IDC with bare hands.
Past me: for my next trick, watch as l use bell wire as male duponts and inhale the magic smoke
Great learning!
Dupont with duct tape!
