The main parameters:
Power: DC 6.5-15V (depending on the required output power), eg. power adapter, switching power supply, battery, etc. The recommended current is more than 3A.
Bass output power: maximum 25W, it is recommended to use 4-6 inch, 4-6O 20-50W subwoofer speaker.
Left and right channel output power: 6W+6W, it is recommended to use 2-4 inch, 4-8O 3-25W full-range speaker.
The above power requires about 13.5V power supply (Suggest PSU>13.5V DC).
The left and right channels use a low-power enthusiast audio dedicated chip TDA1517P as an output stage, which really provides high quality results.
PCB material: FR-4 fiberglass board, thickness: 1.6mm.
Board size: 2.48x1.77x0.78inch/63x45x20mm (LxWxH), excluding potentiometer handle length(Pot. protruding length 0.59inch).
Potentiometer shaft center distance: 0.94inch/24mm, potentiometer mounting hole diameter needs 0.28inch/7mm.
Power input interface: 5.5*2.1DC socket or pad of welding wire
Audio input interface: 3.5mm plug or pad of welding wire
Onboard fixing hole diameter: M3
Package Included:
