Product Description

The 2-in-1 Bluetooth Adapter is an ultra-portable "plug-and-play" solution that requires no external drivers. It is powered via a standard USB port, eliminating the need for internal batteries and ensuring continuous operation. The device features a simple one-button switch or a plug-unplug cycle to toggle between Transmitter and Receiver modes, indicated by a built-in status LED (typically Red for TX and Blue for RX). Its small form factor makes it an ideal travel companion for long car trips or using wireless earbuds with airplane entertainment systems.

Key Features

Dual-Mode Functionality: Easily upgrades any legacy audio equipment into a modern wireless-enabled system.
Bluetooth 5.0 Stability: Provides faster data transmission and a more reliable signal compared to older 4.2 versions.
Driver-Free Installation: Works instantly on Windows, Linux, and macOS, as well as on TVs and stereos without an operating system.
USB-Powered Convenience: Can be powered by a TV USB port, a car charger, or even a power bank for maximum portability.
Lossless Audio Quality: Supports high-quality audio streaming with minimal compression for a rich listening experience.

Technical Details

LED Indicators: Red light indicates Transmitter mode; Blue light indicates Receiver mode.
Frequency: 2.4GHz.
Compatibility: Compatible with 99% of Bluetooth-enabled headphones, speakers, and smartphones.

Prototyping and Engineering Tips from Robogears

Mode Switching Tip: If your module doesn't have a physical switch, you can change modes by unplugging and re-plugging the device within 10 seconds. The LED color change confirms the new mode is active.
Eliminating Ground Loop Noise: If you hear a "humming" or "buzzing" sound when using this in a car, it is often due to a ground loop. Using a simple Ground Loop Noise Isolator between the adapter and the AUX port will provide crystal-clear audio.
Powering for TV Use: When using it as a Transmitter for a TV, try to power it from a separate 5V wall adapter rather than the TV's USB port if you notice interference, as some TV USB ports share a ground with the audio circuitry.
Pairing Reset: If the device refuses to pair with your headphones, turn off the Bluetooth on your nearby smartphone. The adapter will always try to connect to the strongest known signal first.

Package Includes

1 x 2-in-1 Bluetooth 5.0 Transmitter Receiver Adapter
1 x 3.5mm AUX Audio Cable

Disclaimer

This device does not support hands-free calling (no built-in microphone). It is designed strictly for audio streaming. Ensure your USB power source provides a stable 5V to maintain signal range.
