content: Greetings,I'm working on re-purposing the flight controller from an ar. drone 2.0. I need to identify one of the connectors so I can order a male connector and order it. Pictures attached. The connector is 3mm in the narrow dimension. The "D" is 14mm at the widest point, and 13mm at the narrowest. I've drawn lines to better describe the dimensions on one of the photos.I would be eternally grateful of someone could assist me in this endeavor.

content: That's very close. The datasheet shows the pins 1.25mm apart, and I'm measuring the pins as only 1mm apart. I think it's a good starting point, I may be able to browse that type of connector on mouser and find the right one.I must say there are WAY too many types of connectors in the world. It's annoying.Edit: I think the header is this onehttps://www.mouser.com/ProductDetail/TE-Connectivity/1-1734595-2?qs=sGAEpiMZZMs%252BGHln7q6pm9XXV%2FJjz6YwtPlLsTZCgl0%3D(roughly, the one on mouser is a black plastic, not that it matters).However, it doesn't indicate what male connector plugs into that. Is there some trick to figuring out what plugs into the header?

content: Just want to make sure your measuring centre to centre of those pins. I'm sure you are but I've run into this issue before.Tryhttps://www.amphenol-icc.com/media/wysiwyg/files/documentation/datasheet/boardwiretoboard/bwb_minitek_1_00mm_wtb.pdfFound a dimension datasheethttps://cdn.amphenol-icc.com/media/wysiwyg/files/drawing/10147606.pdfLooks pretty darn close.

The caliper may be accurate to 0.01mm but the lower jaws are kind of big for this type of measurement. I did the measurement under my microscope so I think I got it right, but it's possible I didn't.

content: Measuring pixel lengths of the lines in the images confirms that the spacing of the header is closest to 1mm, if the connector is indeed 14mm across. Or you could check what fits into the bigger connector to the left, since it seems to have precisely twice the pitch of the header on the right.

content: Quote from: kelemvor on February 24, 2020, 02:25:31 pmI know what you mean.I have a digital micro scope that has a caliper tool built in . So I just use that on screen .Really handy for people with poor eyesight.One solution is to measure from one side of one pin to the same side as the other pin. Another solution is to measure the thickness of one pin and add that measurement to the distance between the 2 pins. All equally as accurate .

content: Quote from: Jwillis on February 24, 2020, 10:01:59 pmThat's a pretty sweet feature! I was lead to believe it had to be a binocular optical scope to be effective for soldering because of depth perception and time delays. Was I mislead? I guess it doesn't really matter since I already bought the scope, but I'm curious.

content: Quote from: kelemvor on February 23, 2020, 05:30:30 pmYes, there are a lot of connectors in the world, sorry.If it's 1mm, it might be our M40-3011246 - design looks similar to your picture:https://www.harwin.com/products/M40-3011246/If it is, then the mating half is the female cable housingM40-1101200, and that will need crimp contactsM40-1000046, which we also sell as a pre-wired contacts as there is no hand crimp tool (contacts being so small). The pre-wired contact part numbers allstart M40-9, with choices for wire length and single or double ended. Each of the product pages will show you stock at authorised distributors.Hope that helps!
