Cheap USB Type C connectors @ LCSC

Hi all,
The last years I’ve sampled some parts from and it looks to be an interesting alternative/supplement to Mouser, Digikey, RS & Farnell. After looking over some samples of USB C connectors from them, I came to that I’ll only use USB C from here on in my projects (unless clients insist on something else).

So I laid out some simple breakout boards in Kicad to test some of these parts. $0.14 for a USB C power connector or $0.24 for USB 2 on Type C is quite tempting, so I wrote up some of my thoughts on my blog. If you have an interest in USB Type C, please have a look and provide some feedback? I also added some experiences from laying out a USB 3.1 SuperSpeed Hub, so it’s hopefully an interesting read for anyone curious.


I’ve also been making use of these for USB2.0 FS stuff. They work good.

Those were quite cheap @LukeBeno? I noticed that the free shipping is 30-50 days and that express shipping starts at $46.86? What did you choose and how long did it take?

With LCSC, I ordered 13 different products (80 items) and paid $29.85 for DHL. Slow shipping from LCSC is just a few dollars and took 12 days to Norway.

For low volumes, I thought that 24.5 cents is pretty cheap, of course there are probably lower cost Micro USB’s out there or other parts from LCSC like you identified. At a minimum I thought it was a fair deal.

I was introduced to them scrolling through Twitter. It looked like too good of a deal not to try so I just impulsed 100 with the inexpensive shipping. It really did take a long time to arrive, 30 days at least but that was OK because I was just planning to use it when it arrives. Since doing the design, I stocked up on more of them while the first 100 were consumed.

It’s a habit that I’m in now, when I see interesting parts for a good price, I’ll just buy some large quantity of them with the slow shipping.

46.86 for DHL is quite a lot just for these connectors, in this case it doesn’t make sense, I would just get the more expensive but equivalent part on Digikey:

LCSC is great too and their speed/shipping cost is low, I just bought a few reels of buck regs and mosfets from there. This is the same habit, standardize on a 6cent buck regulator, but a reel of 1000 (just $60) and have prototype parts for a long time.

I have plenty of packages arriving in my mailbox for items that I completely forgot that I ordered… Maybe I have a problem…

Hehe. You’re not alone with that habit :wink:

Ironically between typing that response and now I purchased 60 haptic actuators:

Thanks for the experience report and the breakout board designs, Jens. That’s really useful. Sounds like I’ll be steering clear of USB 3 for now. It sounds hard to get right!

@ian USB 3 is only hard if you need those fast speeds, but if you do (or have a client that needs it) it can be good to know that it’s more expensive both in terms of hardware and likely also in amount of work :wink: I also think that I’d do it faster the second time around.

It took 3 PCB’s over 2 months to implement the 3.1 Hub correctly, but I also did other projects at the time. I didn’t count the hours for the Hub specifically (as there are other things on that board also) but it wasn’t too bad. I got great support from TI and I usually do, so I prefer to use hardware from them when I design something where I have limited experience.

Got the first boards back:
I just ordered new files to test the two footprints that needed tweaks. 99% certain that these will work perfectly :wink:
