I guess taking a poll of sorts to gather all the people who have used microSD sockets in their projects.
The main reason is because Im looking for one.. and would like a matching Eagle package to go with it..
So far.. I ave found many on-line.. (but not so many with matching footprints/packages for Eagle.... or the part just inst made any more..etc)
Im hoping to find one with somewhat decent access to the pins for manual soldering (located either in back or large opening in top cover to gain access to pins)
I have tried/found the following parts:
DIPMICRO microSD socket: (pins in back)
1.) has Eagle package
2.) in stock 3.) too wide for my current project (wider than normal)
SPARKFUN microSD socket: Style2 (pins in the back)
1.) has Eagle package
2.) right size 3.) no longer produced/discontinued
SPARKFUN microSD socket: Style2 (pins in the back)
1.) has Eagle package
2.) right size 3.) no longer produced/discontinued
3M microSD socket: 3M 2908-05WB-MG (found in Adafruit library)
1.) has Eagle package
2.) right size 3.) no longer produced/discontinued
WTH!!!???
following the Ladyada/partfinder link..
I find this @ digikey:
Digi-Key Part Number 101-00660-68-6-1-ND
Quantity Available: 2,761
Manufacturer: Amphenol Commercial Products
Manufacturer Part Number: 101-00660-68-6
maybe a replacement for the 3M versions? they seem to be very similar? having the same 'openings' at top to gain access for pin soldering?
if I cant find anything else/better (pins in back..keeping small width).. with a macthing Eagle package this is what I'll go with..
but figured people with more experience than myself have used microSD sockets before..etc.. figured Id ask what brand, package, library...etc was used.
take a look through adafruits library. I bet they would have one in their eagle library.
Yup just checked. The adafruit library has a footprint for this part
thanks.. (but its on back-order for 3 months!) LOL
Im 'thinking' the Amphenol is the same one??
but would like a more experienced set of eyes.. (same one meaning size and footprint.. seems to have same openings at top too for access to pins.. so Im hopeful since it was a link form the adafruit page for the 3M socket.. but leads to that one?)
my guess is must have the same footprint (otherwise why change it? even though Mouser is getting some in in 3-4 months or whatever,.. I believe that 3M socket is discontinued).. so this is a replacement?
the Digikey image used for the Amphenol one is mis-leading..
(it originally led me to believe it had the same opening in the top/cover to give access to the pins as the 3M version did).. but the data sheet shows a different opening..
Also found this off digkey:
So I guess my only option at this point is:
A.) (wait the 3-4 months for Mouser and hope the date doesnt get pushed back out?... not optimal) lol
B.) try to order some of the 'replacement' Amphenol microSD sockets.. (which I believe the Adafruit part/package will work for this).. and 'hope' I have enough space to get to the pins to solder?
If I hadnt gotten feedback that the hinge type microSD sockets werent that great.. Id try to use one of those.. (open it..access to pins I read)
anyways.. talking outloud here.. (maybe someone will see some light at the end of the tunnel...lol)
I think in order for us to actually help you to a good point, we need to know what the "right size" is. Alot of microSD cards are put on using a reflow oven. And if not that, then the most "manual" it gets is a heat gun. Generally a soldering iron never touches a microSD socket.
What is the "right size" that you are looking for. I hope you aren't looking for a .1" spacing between these pins, if so good luck. You will need some sort of breakout board for that. If you are, the closest thing to it is this, SparkFun microSD Transflash Breakout - BOB-00544 - SparkFun Electronics
that 3M one is 'perfect'..(so is the Amphenol one) and most others are the same width, that I have in front of me or have checked.. (except for that DIPMICRO one, which is wider than normal..etc)
I dont have the exact dimension/space.. but I recall it being 15.2/15.4 space/room for the pads/footprint for it, off the top of my head..
if there are components on the top side of the board & the microSD socket is onthe bottom how do you reflow? most people I talk too have used a soldering iron with a fine tip..
or have used microSD sockets with the pins located in the back
yes 14mm seems to be the norm.. (DIPMICRO was alot wider than that)..
I have room for roughly 15.2-15.4mm I think (including all GND tabs on cover...etc..etc)
I have looked at many different sockets over the last few days...
outside of small width/size differences.. a majority have pins 'under' the case/socket....
the initial focus of finding one with pins in the back was a failure.. DIPMICRO was the only one I found with sufficient length on the pins located int he back.. (Sparkfun Style2 were barely sticking out and arent even available anymore)
Outside of the 13.2mm one.. I dont see any difference between those and the ones I posted/have posted lately. (first one looks very similar to the one I posted above (Amphenol) ??) maybe not the staggered pinout..but the same 'opening' to access the pins for soldering.
I thought I had read that NEWARK has Eagle parts on their pages?? (where? all parts? or only a select few?)
Also.. those last links are supposed to be hinged type sockets?? (how so?) what makes you say that? I see nothing in the titles.. and nothing in the data sheets?
Still have yet to see a hinged socket eagle part too.
@boredat20-
Yes I have made a few Eagle parts before.. .. usually a mix-n-match/merge of other parts/footprints though..
If I 'have' too... thats thr route I'll take.. but I dont want to re-invent the wheel..
And Global Connector Technology, popped up while searching
Bottom one listed is Hinged! But no longer available.
Newark does have Eagle symbols for some parts. A lot of times they do not tho. These look to be in the NOT category.
Pick one, get going on the footprint
