And the best part is that you don't even need a connector, you can just build it right into your PCB! USB-A also lets you do a PCB-only connector, but if you're doing anything that requires a cable instead of just plugging directly into a port, it's a lot more annoying to require a USB-A extension cable than any USB-C cable.
- grrrrrbox 4y agoWhat PCB thickness? Got a footprint?
- jmgao 4y ago0.8mm, https://github.com/jmgao/PCB-USB-C https://github.com/jmgao/PCB-USB-C
- grrrrrbox 4y agoThank you!
- prutschman 4y agoThe Eagle one yours is based on says it needs 0.6 mm PCB to work. Is it just close enough not to matter?
- jmgao 4y agoAnnoyingly, the USB-C midplate is specified at 0.7mm. In my experience, 0.6mm boards are too thin to make a reliable connection. Going thicker has worked perfectly with all of the cables I've tried. I suppose there might be some risk of damaging your cables, but it doesn't seem too likely to me (the spec is 0.7 +/- 0.05), and I haven't had any problems.
- anyfoo 4y agoDo you have an example for such a "USB-C edge connector"? Intuitively I would have said that common PCB thickness is too large, or do I misunderstand what you mean?
- jmgao 4y agoYeah, you need a 0.8mm thick PCB, but everyone can do that now (JLCPCB and oshpark both do it for the same price as a regular 1.6mm board). Here's a footprint: https://github.com/jmgao/PCB-USB-C https://github.com/jmgao/PCB-USB-C
- LeifCarrotson 4y agoYou can also do this with thicker PCBs (2.4 or 2mm, nominal 2.235mm, 1.6mm works with a good USB cable or a shim) to form a USB-A male connector, eg: https://eleccelerator.com/usb-business-card/ https://eleccelerator.com/usb-business-card/ http://goodfet.sourceforge.net/hardware/goodfet31/ http://goodfet.sourceforge.net/hardware/goodfet31/
- anyfoo 4y agoSweet, I will consider that next time I need something USB-like, thanks!
- Eduard 4y agoI need photos to understand this, including one where a cable is connected to it
- jmgao 4y agoSure: https://photos.app.goo.gl/CerrZNcQiQE254pTA https://photos.app.goo.gl/CerrZNcQiQE254pTA
- spookthesunset 4y agoVery cool!
