Welcome Andy777! You might get a better response if you drop your question onto one of the Forums here - answers would just get swamped.  :beer2:

Where to buy Crius AIOP V2 molex connectors??

Started by Grimbo, Wednesday,March 06, 2013, 11:25:35

Previous topic - Next topic


Hoping someone can point me in the right direction here.

I bought a Bluetooth module for my Crius AIOP V2 from RCTimer.  Unfortunately I didn';t pay much attention to the connector, I was more interested in the baud rate at the time.  Of course, now I have it I see it comes with a  UART TTL socket which (even though the board itself is marked "Crius") is no good as the board itself is some sort of Molex connector.

Anyone know where I can get the right Molex connector (or a spec or a part number), preferably with fly leads?  Better still, a molex to uart ttl converter (if such a thing exists)?   

I';m guessing that these would have come with a newly bought board but as mine is inherited and did not have all the cables/connectors I don';t have that luxury.

Thanks for any help/advice


Hi Grimbo and welcome to the forum Build Your Ow Drone have a selection of the leads available you will probably have to join 2 leads together  ~~



Thanks Gaza.  I did look there and unfortunately I cannot find any molex on their website.   I';ve left a message on their landline and hopefully they';ll get back to me. 


I thought all the various gps leads he does are molex connectors   :hmm:


Looking at the descriptions of each one they all appear to be jst.  Site search for molex gives no results.

And they have not called me back (so i dropped them a line, but no reply yet) so the search continues.

There are a couple of places in the US that may help.  I';m not sure about this one as it is a "generic" 1.25mm:  http://www.readymaderc.com/store/index.php?main_page=product_info&products_id=627

but otherwise it will have to be this: http://www.rc-connectors.com/index.php?main_page=index&cPath=108&zenid=lb58qsbos8dm2j8sk8dardjhd0 and I will have to make it up, not something I';m confident in..

I may just buy both, though I object to $9 cost to ship a $2 item.  I';m going to end up paying around £8 each for something that should be pennies.  Ah well.



I got some from that Peter King chap that builds quads as I also got my Crius board used, I';ll PM you his email addy.


Please see post http://www.multi-rotor.co.uk/index.php?topic=1607.msg12733#msg12733

You get the pre crimped leads for £8.29 per packet of 10 which means that 83 p per lead.
You get the housings for (average 0.23) each (minimum qty 5).

For a set like the one that I';ve used you pay (4 way housing with 4 leads) you pay £3.55. It seems a little expensive but....

Hope that this helps.

BTW In BYD the stock is ZERO at this moment.




Ok, here';s an update:

Martin of BYOD called me back:  they do not have Molex, they are all jst.

But. got in contact with Peter King and he is sending to me a full set of molex with fly leads, all made up and ready to go,his price was more than reaonable and they';ll be with me tomorrow.

So, I';m a happy bunny.

Thanks all.




Is there a web site for Peter King please,Marty.  :scotland:


AFAIK he doesn';t run a website, just advertises on Ebay and Youtube, I';ll PM you his email address ~~


If you have an old PC awaiting recycle, open it up to find lots of goodies.


Peter is a good guy. I';ve had a few things from him. Very helpful and knowledgeable. Also some great YouTube how to videos. Think he gets his stuff from rctimer.

Just to help anyone else out I have a method that works real well. I have built two of these copters so far and the first time got tired of waiting for the snail mail from china. I used these to connect the correct wires with the supplied molex conectors. When the connectors came in the mail they have sat in the plastic.

Friends dont let friends use NTMs.

I';d strongly advise against those. They';re designed for thicker solid core wire, not the tiny multistrand on a molex. Internally they have a blade designed to cut through the insulation (to save pre-striping), and crimp the wires in place. With skinny multistrand, there';s a good chance they';ll cut the wire. It may still have physical contact so appear to work, but could fail unexpectedly in flight.

Not to mention, they';re clunky, ugly and big.

If you';re really not comfortable with a soldering iron a) start practising - it';s not that hard, and a really valuable skill in this hobby, b) consider using an ribbon cable IDC (insulation displacement connector) that is designed for multistrand wire, (if not for this purpose).

You can easily fit two strands per pin to join them together, and they come in multiple sizes. This would be far from my first choice for joining wires, but it';s a much safer kludge than these yellow things.

Better still, use the ready made connectors I mentioned above:
