CQRobot JST XH 2.54 mm Pitch 2-Pin/3-Pin/4-Pin Electronic Connector IC Male Plugs, Female Sockets Housing and T-Shaped Crimp Terminal Kit. 90 Sets/460 Pieces Wire-to-Board Adapter Cable Assembly.

These JST connector/sockets are a really nice was of providing interconnect between parts in an electronics project.My current project uses 2 different JST connectors, one is a 2 pin connector for a battery and the other is a 8 way connector to a display. These are really nice connectors, the quality is fantastic, but....I hate making the cables, the pins are really fiddly to crimp. I originally used the engineer pa-09 crimping tool which seemed to be the tool everybody uses, but it's fiddly to use and sometimes the crimp fails.I have just discovered the IWISS 3220M crimping tool which is an order of magnitude better and doesn't exhibit the failed sleeve crimp problems that occasionally happen with the engineer tool.With the right tool, these are just about bearable to make, if you don't have the right tool, you are in for a world of pain.I've included a picture of a number of cables I crimped with parts from this kit.

I have used one, it was bit difficult to put together. Also, i am new to this, so if you have more experience then buy it it is worth the money.I will get it after few try's and 4 stars, because of no instructions, for noobs like me.BUT don't get me wrong it is worth of the money!

Wow, these are small for crimping. Needed two lenses in my magnifier headset (old eyes)Useful small set in a box

Great little connectors, using them to wire up the fans on my 3D printer. Glad there are so many in the box as it took a few go to get them to work properly. Once I mastered the technique they're easy to use. If you plan on using a lot of these get the proper crimping tool. You can do it with pliers but it's a little awkward.

Good value for the money. I think these will last a lifetime. I used these to make adaptors for my Geeetech i3 3D printer. I can now use standard fans with Molex style plugs on. No doubt I will find other uses for them.

It is ok

good

I use these for many upgrades of my Ender 3 printers. They work very well and quality is very good. No complaints whatsoever.
