The **RUSB2CC2MB** refers to a specific type of USB cable assembly, typically categorized as a **USB 2.0 Type-C to Type-C Cable**. This component is widely used in power delivery and data synchronization for modern electronic devices. Below is a detailed breakdown of its electronic specifications and features. --- ### 1. Technical Specifications This cable is designed to meet the USB 2.0 standards, focusing on compatibility between two USB-C ports. | Feature | Specification | | :--- | :--- | | **Connector A** | USB Type-C (Male) | | **Connector B** | USB Type-C (Male) | | **Protocol** | USB 2.0 | | **Data Transfer Rate** | Up to 480 Mbps | | **Standard Length** | 2 Meters (approx. 6.5 feet) | | **Power Rating** | Typically 3A (60W) or up to 5A (100W) depending on E-Marker | ### 2. Electronic Internal Components The functionality of the RUSB2CC2MB is governed by several internal electronic parts: * **E-Marker Chip (Electronic Marker):** High-quality versions of these cables contain an IC inside the connector housing. This chip communicates with the power source to define the cable's current-carrying capacity (e.g., telling a laptop it can safely pull 60W or 100W). * **Twisted Pair Wiring:** For data transmission ($D+$ and $D-$ lines), the wires are twisted to minimize electromagnetic interference (EMI) and signal degradation. * **Shielding:** To maintain signal integrity at 2 meters, the cable includes an aluminum-mylar foil and a braided copper shield to prevent "crosstalk" from nearby electronic devices. * **CC (Configuration Channel) Lines:** These are the critical wires that allow the two connected devices to "negotiate" roles (host vs. peripheral) and power levels. ### 3. Pin Configuration (USB-C) While USB 2.0 does not utilize all 24 pins of the USB-C physical interface, the connector layout remains standard: | Pin Type | Function | Description | | :--- | :--- | :--- | | **VBUS** | Power | Carries the 5V-20V power supply. | | **GND** | Ground | Return path for the power and signal. | | **D+/D-** | Data | Differential pair for USB 2.0 data signals. | | **CC1/CC2** | Configuration | Used for cable detection and power negotiation. | --- ### 4. Use Cases * **Charging:** Connecting a USB-C wall adapter to a smartphone, tablet, or laptop. * **Peripheral Connection:** Linking a USB-C docking station or external hard drive to a PC. * **Microcontrollers:** Powering and programming development boards like the Raspberry Pi 4 or ESP32-S3.
