Small-sized Bluetooth audio module stereo car lyric music phone | ANS-BT303M
The ANS-BT303M is a small, high-performance Bluetooth 5.3 audio and data integrated receiver module developed and manufactured by Ansiot Technology. This module breaks through the limitations of single transmission, perfectly integrating high-quality audio processing and efficient data interaction. Using standard UART as the programming interface, it supports customers in quickly reading or writing module configurations using flexible AT commands. The ANS-BT303M is specifically designed for smart terminals with comprehensive requirements for size, sound quality, and screen data display, helping manufacturers significantly shorten product development cycles and endowing terminals with more powerful intelligent human-computer interaction capabilities.
Product Advantages:
1. Dual-track Data and Audio Operation: Utilizing the new Bluetooth 5.3 architecture, it perfectly supports data interaction (seamless switching between command mode and pass-through mode) and high-fidelity audio (music playback + phone calls) in dual-mode concurrency.
2. Compact Size, Multi-interface Ecosystem: The compact hardware package significantly saves PCB board space. The input supports both Bluetooth and USB high-efficiency modes, while the output provides standard high-fidelity stereo output, compatible with various mainstream hardware boards.
3. Deep Human-Machine Interaction Control: Built-in features include precise playback progress synchronization, multi-dimensional channel sound effect adjustment, one-click AI voice assistant wake-up, and an ultra-low power deep sleep mechanism to effectively balance overall device power consumption.
4. Multi-dimensional Visual Information Output: Bluetooth supports real-time output of lyrics, song titles, and caller ID data via serial port. This information can be directly and stably displayed on the terminal screen, greatly reducing the development difficulty of screen UI interaction interfaces.
5. Rich Software and Hardware Customization Functions: Deeply supports MUTE (mute) function control, advanced EQ sound effect adjustment, and highly practical Chinese/English bilingual intelligent voice broadcast customization to meet diverse commercial needs.
