-1002L MINI Bluetooth 5.0 DC 5-24V Wireless o Digital Power Amplifier Stereo Board 100Wx2 Bluetooth version 5.0 provides higher transmission efficiency and a stable wireless connection with a transmission distance of up to 15 meters without obstruction. Features an efficient heat sink design for effective heat dissipation. Equipped with a potentiometer for volume adjustment and an on/off switch for easy control, making it ideal for DIY speaker projects. If used in a metal enclosure, ensure the Bluetooth antenna is properly extended. Uses a copper DC connector designed to handle high current with minimal heat generation. Incorporates four 470uF high-quality capacitors to ensure stable power storage and continuous power supply, supporting consistent o performance. The DC power input with cable allows compatibility with standard power sources. Even without a dedicated adapter or battery, the board can be connected using compatible power supplies. Operating Voltage: 5-24V (Compatible with 9V, 12V, 15V, 18V, 24V power adapters; higher voltage recommended for optimal performance) Power Output: - 12V: 24W + 24W (8 ohm), 40W + 40W (4 ohm) - 15V: 32W + 32W (8 ohm), 60W + 60W (4 ohm) - 19V: 64W + 64W (8 ohm), 80W + 80W (4 ohm) - 24V: 72W + 72W (8 ohm), 100W + 100W (4 ohm) Product Name: HIFI Bluetooth Digital Power Amplifier Board with Filter Model: -1002L Chip Solution: Domestic Built-in Filter: Yes Compatible Speakers: 50W-300W, 4 ohm to 8 ohm Channels: Stereo (Left and Right) Bluetooth Version: 5.0 Bluetooth Range: 15 meters (unobstructed) Protection Features: Overheating protection, short circuit protection Color: Black Material: Metal + PCB Package Includes: 1 x Bluetooth 5.0 Digital Amplifier Board 1 x Shell 1 x Screwdriver 1 x Power Cord Note: The power switch on the board serves as a standby switch. When turned off, the device enters a low-power standby mode. To completely disconnect power, unplug the DC power source. For long-term storage, remove the DC plug. For optimal performance, ensure sufficient o input and adequate power supply voltage and current. Higher supply voltage results in higher output power. Output power varies depending on speaker impedance. With sufficient power input, higher impedance speakers will produce relatively lower output power. The package includes only the items listed above. Other accessories or products are not included. Note: Lighting and display differences may cause slight variations in the color of the item as shown. Measurement tolerance: +/- 1-3 cm.
