✨ Key Features

• Amplification: PAM8610 (Class-D) stereo amplifier providing 2x 10W output power.
• 4-Layer PCB Stackup: 4-layer board design with dedicated power and ground planes:
  • F.Cu (Top): Signal + GND fill
  • In1.Cu (Inner 1): GND fill
  • In2.Cu (Inner 2): Power
  • B.Cu (Bottom): Secondary signal + GND fill
• Supply Voltage Range: from 9V to 12V DC via standard DC05 DC Barrel Jack.
• Volume & Power Control: 10K logarithmic potentiometer with an ON/OFF switch.
• Connections: 3.5 mm AUX stereo input jack and screw terminal blocks for Left (L) and Right (R) speakers.
• Clean sound: Bulk 2200 µF electrolytic decoupling capacitor on power supply lines + LC output filters (33µH inductors) for ripple noise reduction and high signal fidelity.
