content: USB type-C socket design was finalized about half a year ago but I still cannot find any sources. Digikey has itlisted($4.69/pc!) but with no stock. I can see someone selling it on eBay with a breakout board. When do you think it will be more widely available on the market? What do you think about the standard? Will you use it in your designs?

content: Quote from: owiecc on April 28, 2015, 03:53:16 pmThe concept is great, especially reversibility and the power capabilities. But it's got a while before it gets to a critical mass. Until then it's USB standard and micro as far as I'm concerned for some time.e

content: Give it 2-5 years, and it will be everywhere.As soon as consumer chipsets for motherboards and portables will support Type-C natively without any extra interface chips, it will get popular.

content: Quote from: owiecc on April 28, 2015, 04:56:54 pmI was thinking the same. 20V 5A is something which is nice, backward compatibility is nice. I did not see any mayor western manufacturers having Type C plugs in their catalog. molex, samtech, te, all the usual industrial grade computer connector manufacturers seem to avoid it?There are no ESD solutions for it, no power delivery controllers (TI has 60+ for usb charging, no for power delivery?). I dont know what is the deal with it, but as I see, even high speed chips are rare.It seems stupid to me, there are valid applications where this could be used.

content: TI does have stuff for both PD and USB 3.1, it's just under NDA. Similar with other vendors too.I think we will see more stuff later this year.

content: They're probably all tied up in orders for large manufacturers. Once they become more prominent and more suppliers are producing them, then we'll be able to get them in the usual places. For now, unless your name is on the business card of a large company, no go.Too bad too, I wanted to put one in a recent project...just for fun. I didn't NEED USB C, but it would have been neat.

content: I will probably keep shipping stuff with Micro for about 2-3 more years. Type-C will take a long time to get critical mass, since we have 15 years of the previous design. And type-C 3.x will require compatible PHYs for pin swapping, so that won't happen for quite a while.

content: Quote from: marshallh on April 29, 2015, 09:03:02 pmThe pin swapping is built into the connector. It has 12 wires, 24 pins in the connectors and 12 pads on the PCB. It is a beauty. Finally they reduced that 4 dimensional connector into 3 dimensions.

content: Quote from: Monkeh on April 29, 2015, 10:40:20 pmWait, what? Half the connections is SMD the other half is TH.Ok, I was wrong.I've also got a mail today from NXP where they blab about the Type-C. I guess, this might speed up the information spreading, no-one likes to lose market because of it.I wounder, if anyone knows if we only have a 2.0 slave device, with an extra power delivery controller, Can we get 20V 5A through this connector?
