Mic/Earphone Socket to USB 2.0 Sound Card

Instant USB Audio Expansion: Adds dedicated 3.5mm microphone input and headphone output jacks through a single USB 2.0 port, bypassing damaged onboard audio ports or missing analog audio jacks.

Driverless Plug-and-Play Setup: Works immediately out of the box with zero software or driver installation required—simply plug the USB Type-A connector into any host system or single-board computer.

Integrated Flexible USB Lead: Features a short, flexible cable extension between the USB connector and audio jack housing to prevent port strain and avoid blocking adjacent USB ports.

Stereo Headphone & Mono Mic Support: Outfitted with standard color-coded or icon-labeled 3.5mm TRS sockets supporting stereo audio playback and mono microphone recording.

Low-Power Bus-Powered Operation: Powered directly via the USB bus, eliminating the need for external power supplies or batteries.

Housing & Cable Shielding: Encased in a lightweight, impact-resistant molded ABS plastic housing with a flexible PVC cable jacket.

Connector Care: Insert 3.5mm audio plugs firmly into sockets until fully seated. Avoid tugging on connected audio cables to prevent internal solder fatigue.

Electrical Safety Precautions: Connect to standard 5V USB host ports. Keep audio sockets free of dust, lint, and liquid moisture to prevent audio static or grounding noise.

Environmental Limits: Operating temperature range is 0°C to +40°C. Store in a dry environment away from direct heat sources.

Essential Audio Upgrade for Raspberry Pi: Market to Raspberry Pi 4B, 3B+, and Zero users who need dedicated analog microphone input (which Pi boards lack by default) or cleaner headphone audio output.

Easy Repair & Workstation Solution: Position as a low-cost replacement fix for laptops or desktop PCs with broken internal sound cards or faulty 3.5mm aux jacks.

Recommended Cross-Sell Add-ons: Pair with Raspberry Pi Mainboards (Pi 4B / Pi 5), 3.5mm Aux Audio Cables, and USB 3.0 Hub Expansion Modules.

Broad Operating System Support: Emphasize universal plug-and-play operation across Raspberry Pi OS, Windows, macOS, Linux, and Android OS.
