For maximum advertised output, a suitable 24V high:current power supply is recommended by one vendor; at lower supply voltages, available output power will be lower.
🔹 Pin Configuration & Wiring
🔹 Applications
This component is engineered and suitable for:
- •Microcontroller interfacing (Arduino, ESP32, Raspberry Pi, STM32)
- •IoT telemetry, environmental monitoring, and smart home systems
- •Robotics navigation, obstacle detection, and motion sensing
- •STEM education, university electronics labs, and maker prototyping
🔹 Package Includes
- ✓⚠️ Precautions Verify the exact input voltage requirement of your AP-55 version before powering it. Do not exceed 24V DC where the board specification limits input to 24V. Check power polarity carefully before connection. Use speakers with a compatible 4Ω–8Ω impedance. Do not short-circuit the speaker output terminals. Ensure adequate ventilation during high-power operation. Use a suitable high-current power supply for high-output operation. Do not connect the speaker outputs together or directly to ground. Keep the board away from moisture and conductive materials. Incorrect wiring or excessive voltage can permanently damage the amplifier IC.
