+USB-C (Power + Sideband) Cable Signal Reference

+This cable is optimized for Power Delivery and Analog Sideband signals.

93
+It lacks standard USB 2.0/3.0 data wires.

+### 1. Power & Logic
96
+- **VCC (VBUS)**: Main power rail. High-current capable.
97
+- **GND**: Common ground for power and logic.

99
+### 2. Configuration (The "Smart" Part)
100
+- **CC1 / CC2**: Configuration Channels. These allow the cable to:
101
+ - Work in any orientation (no "flipping" required).
102
+ - Negotiate high current (up to 3A or 5A) from PD power banks.

104
+### 3. SBU (Sideband Use)
105
+- **SBU1 / SBU2**: These are auxiliary wires.
106
+ - **In Audio:** They often carry microphone or ground signals for headsets.
107
+ - **In Video:** They carry the "handshake" data for DisplayPort.
108
+ - **In DIY:** These can be used as extra signal wires for sensors,
109
+ but they are very thin and NOT for power.
