Quantity : 1 High-concerned chemical : none Package : SOP Supply Voltage : DC 3.3-5V Type : Module Brand Name : DIY NOW Origin : Mainland China Condition : New Features: 1. Adopting BT 5.4 low-power protocol, the standby current is as low as 5uA. 2. Supports low-power encoding protocols, providing better sound quality and reducing power consumption by over 30%. 3. By optimizing channel hopping and other methods, it is possible to effectively avoid lagging and disconnection issues.. 4. Stereo input, supporting high fidelity dual channel audio transmission. 5. Wide voltage design, compatible with 3.3-5V power supply, strong adaptability. Product Introduction On the basis of inheriting the core functions of previous versions (such as BT 5.2LEAudio), the BT 5.4 audio module optimizes the three core requirements of low-power transmission, anti-interference ability, and connection flexibility. It adopts BT 5.4's exclusive low-power encoding protocol (such as LC3 encoding), which can reduce power consumption by more than 30% compared to traditional SBC encoding under the same sound quality; With the help of "broadcast channel optimization" technology, the standby current of the module can be as low as 5uA or less, and the current during continuous audio playback can be controlled at 10-20mA (depending on the transmission rate). Through "channel hopping optimization" and "data packet retransmission mechanism", the audio transmission packet loss rate can be controlled below 0.1% in complex wireless environments (such as multiple WiFi devices and 2.4GHz frequency band interference), avoiding lagging and disconnection problems. Parameter: Product Name: BT 5.4 Audio Receiver Module BT Name: SFT-BT5.4.1 Working voltage: DC 3.3~5V Input method: True 2.0 dual channel stereo Finished product specification: 35mmx32mm PCB substrate: 1.2mm thick FR-4 fiberglass board Installation method: Horizontal welding installation Receiving distance: 10 meters in a straight line distance Kind Reminder: 1. Avoid installation in metal enclosed spaces as it may affect the reception of BT signals, resulting in intermittent or silent sound. Pay attention to the positive and negative poles when connecting the power cord. Please use it within the calibrated voltage range. Incorrect connection or high voltage may burn the board. 2. After BT power failure, there is no need to search again, and it comes with a memory connection function. Package Include: 1X motherboard 1X 5Pin Pin Pin XH2.54 1X remote control (optional with or without remote control combination) label:yes
