USB Type-C Plug Breakout - USB 3.0

by Solder Party

This plug and breakout board provides an easy way to extract signals and power when plugged into a USB Type-C Receptacle.

By default, the CC pin is connected via a 5.1K resistor to GND (-), meaning the plug identifies as a downstream port, and the upstream port will provide up to 1.5A at 5V. You can replace or move the resistor to pull the CC pin to VBUS (+) or change the pull value.

The 3.0 variant of the breakout board contains only two SuperSpeed differential pairs (RX2+/- and TX2+/-), meaning only single-lane mode is available.

As per the USB Type-C specification, the plug has only one pair of D+/D- pins; it’s up to the Receptacle it's plugged into to connect them together or use a mux for more advanced scenarios. Similar with CC and VCONN pins. The SBU pins are not available.
