- What do the 3 symbols (circle, square, triangle) in the USB Type-A plug . . .
What do the 3 symbols (circle, square, triangle) in the USB Type-A plug represent? Is it power- data-related notifications or just universal identification for USB?
- Input Power Pin not Driven by Output Power Pin ERC error in KiCad
Edit: Following the solution from: KiCAD gives error "Input power pin not driven by any output power pins" with VBAT connected to battery symbol, just increases the number of errors I get
- Are USB protocol and connector free or are they patented?
For a hobbyist developing a device, certification is not pleasant I am wondering if implementing USB in any way is patented or needs a certification? I am concerned about both protocol (USB-2,3
- How can I tell charge-only USB cables from USB data cables?
How can I tell if one of these cables is a charge-only USB cable instead of a USB data cable? Ideally, I would love to rely on some visual clue, but I have a multimeter I could use to test the cables with if I knew a good approach to this
- Do I need a license to use a USB-A plug on my power cable?
I want to make a product that has a power cable with a USB-A plug on it There is no USB socket on the device, the cable just enters the device, similar to the HomePod mini The idea is to instruct
- USB usage restrictions - Electrical Engineering Stack Exchange
And all of the other device manufacturers want that, too Is the trident logo free for usage without a Logo License Agreement (this logo does not appear in the logo usage guidelines)? No If you put the logo on a non-compliant device, this will cause harm to the USB community at large They will come after you in order to protect themselves
- usb c - Sanity check for USB-C connector schematic - Electrical . . .
There are many things that could be wrong, but to keep things simple I wanted to ask for feedback on the USB connection first: Electrical engineering is not my main field, so I would very much appreciate it if someone could confirm that this USB-C design looks correct All I need from the connector are the power lines and the D- and D+ data lines
- usb pd - What does this connector symbol mean in a charger schematic . . .
Could somebody explain what symbol JP1 means? iIt is presented in the schematic of the datasheet of a USB-C PD controller I think JP1 symbol is kind of two state connector (normally closed and nor
- USB-C Sink design - Electrical Engineering Stack Exchange
The DMG2305UX and DMMT5401-7-F create an ideal diode and only allow power to source from the USB port USBLC6-2P6 provides ESD protection on the D+ D- and VBUS (Note, the symbol is incorrect, the specific component uses bidirectional diodes Also, TPS2557DRBR provides ESD protection on the VBUS line) USB-7070C is a 16 pin USB type C port
- USB Type-C pins designation - Electrical Engineering Stack Exchange
I am trying to design a USB to Serial converter featuring CH340C IC and I'm a bit concerned whether I have correctly hooked up the SBU, DP DN, and Shell pins Is there any chance that I did everyth
