Finding The JST Connector You Need

In this video I help identify and name the different JST connectors we use in the multi-rotor hobby. There are even more types of JST's but I cover the most commonly used.

Cheaper JSTs with plastic wire...........................

JST's with silicone wire...................

Even after he's gone, he's still helping people out. Thanks, JC, for straightening out the JST mess for me.

Wow! I haven't been here since JC died. You are still giving us help to this day. RIP

Still great info... This is why you are so greatly missed by so many thousands... Rest well my friend.

MARSHALL AMPLIFIER TYPE: Glad I found this. It helped immensely with my own search for an obscure part. I hope you will forgive me for posting this for others who may find it too coming from the same field as myself.

Just for reference for anyone who comes here as I did looking to identify them from their guitar amplifier, Marshall use a version of these on their PCBs in most of their amp models. They chose the slimmest in the range, the "EH" type which isn't shown in the video above as it is obviously a separate application. They are 2.5mm pitch with a 3 sided shroud open all along the whole of one long side on the PCB mounted male socket. It also has two slots on each side, one internal to the shroud and one through it. The wire mounting female plug has two locating/locking ridges down both of its short edges which fit into those slots. The socket also has small vertical ridges along the shroud back wall between each of the terminals while the plug has notches to register with them.

It is amazing how much he taught us. Rest in Peace JC!

There is a bit of a learning curve for JST but after you wade through it is makes sense.
There are series of connectors. The x.xmm values is the pitch or the spacing of the pins
EH - 2.5mm
PH - 2.0mm
ZH - 1.5mm
SH - 1.0mm
ACH - 1.2mm Wire to Wire

There are 3 components to a PCB connector.
The Contacts /pins
The Header/ piece mounted on PCB
The Housing/ The piece that fits into the Header

The ACH - Wire to Wire

Plug Contact and Socket contact remember pins are called contacts.
They have Plug Housings and Socket Housings. look at it like a plug and wall socket.

The Plug contacts/pin fits in the Plug housing.
The Socket contacts are placed in the Socket housing.

So if you jump to 6:15 the beige connector on the PCB is the header. The white connector is
the housing. The contact fits in the housing.

You have to make sure that you order the correct series of contacts. The contacts or pins are either
EH, PH or what ever.

You have to watch as sometimes they will call a small connector JST when its not. That beige header does not look like a JST header.

I'm posting this just to solidify what I learned a few weeks it is the first steps in knowing it.

You just saved my (JST) life. 4 years after video release.

People like you make the internet what it is. Thank you.

[Michael-lxpx]

Thank you very much!!! You just solved a 2 year problem I've been having trying to locate the right JST 2mm 3pin. Found the exact ones I need on ebay and just ordered them. Thanks again!!!!
Up Up n Away,

First of all I really like your videos, very high signal to noise :-)

The way I tell the JST-SH from a Pico Blade connectors is the PB has one or more humps on the back and the JST-SH is flat. Also the JST-ZH (Spektrum Sat) pins are round, where the JST-SH and Pico Blades are flat.

The JST 2.0 common to the hobby would be a JST-PH, popular on nano quads like the Tiny Whoop, et.al.

The JST 2.5 is actually a JST-XH.

The very first connector you showed but didn't name was a JST-RCY, which is commonly used for micro quad battery connectors.

To solve the problem of crappy plastic insulation, I custom make all my cables and hand crimp the connectors (Pico Blades are a real pain) using a Engineer PA-09 crimper.

FWIW, the Pico Blade and JST-RCY connectors are suitable for wire to wire connections. The PB is good for signal ( < 1A ) and JST-RCY for low power ( < 3A ) applications. I like to make my builds modular where possible as I'm often having to repair them (I suck a flying).

I get the connector and pins from Digikey.

I have searched and searched and I think you have just shown the mystery connector I've looked for. Thank you!

[sheabutter]

man this guy was so helpful and full of so much info ... God Bless your soul JC

[babakzekibi]

I just visit your page just to hear your voice brother. Rest in heaven.

[davbra]

Thanks so much for putting this together! I've spent so much time trying to figure out what connector I need for my 4-in-one exc to omnibus and now I understand what I need!

[theMindscapeChannel]

Great job explaining the connector types... been searching everywhere trying to understand these cables and connectors...

[raymondmyers]

Dude. I wish you had posted this 2 weeks ago. I just bought a drone from a swap meet and was trying to figure out what I needed and it took me a couple of hours to try and figure it out. fortunately I did get the right connectors but this video would have saved me a ton of time. thanks for all the great content man.

[BSON]

thanks for the video. JSTs drive me insane

[Daclaem]

how many times did i find your videos when i needed infos, thanks a lot lot dude, rip.

[swapshots]

So glad I found this.! Thankyou JC.! R.I.P.

[SquiddyJ]

This is such a life saver, it even works with Dell OEM PC cases for custom build.. cause Alienware likes to use those for their own motherboard and not for any other so this resolves everything!! Thank you so much!!!
