Communication buses
USB-C
The reversible connector + cable spec; one of the connector options for USB.
How it looks
Real image: CORE3588, rendered by KiCad from our board file
The USB-C socket at the top right of CORE3588, 11 x 12 mm.
- 1USBC1, the USB-C socket on CORE3588 (power and data in).
- 2D5, ESD protection for the data and CC lines.
Real geometry: CORE3588 copper, drawn from our board file (2D plan view)
Its footprint, flat: amber pads are power, data and CC; grey are ground and shield.
- 1The data pair, D+ and D-: each appears twice, once per plug orientation, and the copper joins them.
- 2CC2 ...
- 3... and CC1: which one is connected tells the board the plug's orientation.
How it works
Where it fits
USB-C is the connector; USB is the data protocol; USB-PD negotiates higher voltages over the CC wire.
