content: Like these?http://www.digikey.com/product-detail/en/amphenol-commercial-products/MDT275A03001/MDT275A03001TR-ND/5810354This particular one looks a little short, but they're available in various heights, so you can place components under the card footprint.Tim

content: Why mini PCIe? The mini-PCIe connector is designed as a card edge connector, I doubt there are board mountright anglevertical male connectors for it. The usual way to combine cards with edge connectors is by plugging them into a back plane.It doesn't make much sense to try to use it directly for stacking. There's a stacking PCIe version of PC/104 for instance, but it uses a different connector. It's only PCIe for the protocol and electrically.

content: Quote from: blueskull on June 01, 2016, 04:08:21 amI assumed he wanted pure vertical stacking. In which case he would need a male version as well. Using a backplane isn't really stacking.Trying to find the connector that Asrock uses and building his own backplane with them seems to be the most likely solution then.

They seem to be available at different heights, so you might still have room for components beneath the mini-PCIe module.If you can find the vertical connectors they use on motherboards you could make a backplane, but I can't find them.

content: That black bit in your drawing IS a backplane ... and you'd have to create it yourself by putting two vertical connectors (which are rare) on a PCB.Again, why can't you put a normal mini-PCIe connector on your own PCB and mount the module on top of it?

content: Ah whoops, so to answer my question there are no stacked horizontal mini PCIe connectors?And like I said space on PCB is limited, want to have another mini PCIe connector, so was hoping that you could get a stacked one that would take x2 mini PCIe modules

content: Quote from: ANTALIFE on June 01, 2016, 06:19:00 amI know Gigabyte did it like so:Using a low profile mini-PCIe, then a raised PCIe to go over the top.I don't think there are any true stacked horizontal miniPCIe unless you want to contact TE or another company and inform them that if such a component existed you would buy 100,000+
