Mini digital amplifier board 5V with switch potentiometer.
- Operating voltage: 2.5V-5.5V
- Maximum output: 3Wx2 (5V 4 ohms)
- Board dimensions: Width 30mm / depth 22mm / height 16mm (Dimensions without the potentiometer)
- Efficiency: Feasibility over 90%
The operating voltage should not exceed 5.5V and the power supply should not be incorrect.
