Connectivity Protocols: Supports Miracast (Android/Windows), DLNA, and AirPlay (iOS/macOS). Resolution: Capable of outputting up to 1080P Full HD.

Power: Typically requires a 5V USB power source (often connected to the TV's USB port or a wall adapter).

Operating System: Runs on a localized Linux-based system designed for "plug and play" use with minimal boot time. Key Features

Broad Compatibility: Works with Android 4.2+, iOS 7+, Windows 8.1/10, and Mac 10.9+.

App Support: Generally supports YouTube and Google Home; however, it often lacks support for encrypted streaming services like Netflix and Amazon Prime Video due to HDCP (content protection) limitations.

Dual Modes: Often features a switch (either physical or software-based) to toggle between AirPlay/DLNA and Miracast modes to ensure compatibility with different device types. Use Cases

Home Entertainment: Streaming personal photos, videos, and music from a phone to a big screen.

Business/Education: Wirelessly sharing presentations or documents from a laptop to a projector during meetings or classes.

Gaming: Casting mobile games to a TV for a larger viewing area, though some latency (lag) may be present depending on the WiFi signal strength. Common Troubleshooting

Connection Issues: If the dongle is not detected, users are advised to reboot the 5V power connection or ensure the phone is in close proximity to the dongle's WiFi antenna.

Buffering: Using a "Data Saver" mode in video apps or ensuring a clear line of sight between the antenna and the source device can help reduce latency.

The Rockchip WR002 Dongle is a compact, high-performance wireless display adapter designed to bridge the gap between small-screen mobile devices and large-format displays like TVs and projectors. Powered by specialized Rockchip silicon, this dongle is widely utilized in both home entertainment and professional business environments for seamless, low-latency screen mirroring. Core Technical Specifications

is engineered for efficiency and high-speed multimedia processing, often featuring the following hardware profile:

Processor: Driven by the Rockchip RK3308 chipset, a quad-core CPU with clock speeds reaching up to 1.3 GHz.

Connectivity: Equipped with dual-band Wi-Fi (2.4GHz/5GHz) and Bluetooth 4.0 to ensure stable connections even in crowded wireless environments.

Interfaces: Includes standard HDMI output (typically HDMI 1.2 or higher) and USB 2.0/3.0 ports for power and peripheral connectivity.

Video Performance: Capable of 1080P HD output, with some variants supporting 4K decoding for higher-end multimedia needs. Primary Features and Functions Rockchip WR002 dongle Appendix A — Suggested lab checklist (equipment and

serves as a versatile multimedia bridge, supporting several industry-standard protocols:

Miracast Support: Allows for direct, peer-to-peer wireless screencasting from Android and Windows devices without needing a shared Wi-Fi network.

DLNA Compatibility: Enables users to "push" specific media files—like videos, music, and photos—from a phone or local server to the big screen while keeping the phone free for other tasks.

Low Latency Performance: Optimized to deliver a response time of approximately 80 milliseconds, making it suitable for presentations and casual gaming where lag can be a factor.

Cross-Platform Use: Compatible with a wide range of devices, including smartphones, tablets, and laptops running Android 4.2+, Windows, and other Miracast-compatible OSs. Key Use Cases

Professional Meetings: Used in conference rooms to facilitate BYOD (Bring Your Own Device) policies, allowing presenters to share slides instantly from their laptops or tablets without fumbling with cables.

Education: Teachers can mirror educational apps and videos from a tablet directly to a classroom projector, enhancing interactive learning.

Home Entertainment: Transforms any "dumb" TV with an HDMI port into a smart display capable of streaming content from mobile apps.

Digital Signage: Provides a cost-effective solution for small businesses to wirelessly push advertisements or menus to display monitors. Setup and Configuration Getting started with the Rockchip WR002 is generally straightforward:

Hardware Connection: Plug the dongle into the TV's HDMI port and connect the USB cable to a power source (5V/1A).

Mode Selection: Use the physical button on the device (if applicable) or the on-screen menu to switch between Miracast (Direct) and DLNA (Wi-Fi) modes.

Device Pairing: On an Android device, look for "Wireless Display" or "Screen Cast" in the settings and select the WR002's ID to begin mirroring.

Symptom: After 10 minutes of heavy file transfer, the plastic casing is too hot to touch. Fix: This is normal for the RTL8821CU. It runs at approximately 65°C under load. However, if it exceeds 85°C, it will throttle. Add a small passive heatsink (available on Amazon) to the top of the casing, or use a USB extension cable to move it away from the hot CPU of your SBC.

| Feature | Rockchip WR002 | Generic RTL8812BU | Mediatek MT7668 USB | |------------------------|-----------------------|-----------------------|----------------------| | Wi-Fi Standard | 802.11 a/b/g/n | 802.11 a/b/g/n/ac | 802.11 a/b/g/n/ac | | Max Speed | 150 Mbps | 867 Mbps (ac) | 433 Mbps (ac) | | Bluetooth | 4.1 | 4.2 | 5.0 | | Linux Mainline Support | Partial (vendor needed)| Good (kernel 5.15+) | Good | | Price (approx.) | $5–8 | $12–15 | $10–14 |

Symptom: Streaming audio drops out, and ping spikes to 2000ms. Fix: This is RF interference. The 2.4 GHz band is shared. Force your WiFi to 5 GHz only (if your router supports it). Alternatively, use the command:

sudo iwconfig wlan0 txpower 10

Reducing the transmit power minimizes cross-talk with the Bluetooth antenna.
