Design with Placa Amplificador De Áudio Digital Xh-m544 150w Mono in Cirkit DesignerThe Placa Amplificador De Áudio Digital XH-M544 150W Mono is a high-performance digital audio amplifier board designed to deliver up to 150 watts of mono output. It is based on the TPA3116D2 amplifier chip, which ensures efficient power delivery and high-quality audio output. This module is ideal for driving speakers in various audio applications, such as home audio systems, DIY speaker projects, and public address systems.
This circuit is a mono audio amplifier system. It uses a PAM8403 amplifier IC to amplify the audio signal received from a 3.5mm audio jack and drives a speaker. The audio signal from the left channel (L) of the audio jack is amplified and output through the speaker, while the right channel (R) is connected but not utilized in this mono setup.

This circuit features an Arduino UNO microcontroller interfaced with a 4-channel relay, two IR sensors, a servo motor, an LCD I2C display, a PAM8403 audio amplifier connected to a speaker, and an XR2206 function generator with a resistor and capacitor for frequency shaping. The Arduino controls the relays based on a potentiometer input, displays frequency information on the LCD, and adjusts the servo position in response to the IR sensors. The XR2206 generates an adjustable frequency signal, while the PAM8403 amplifies audio for the speaker.

DC IN terminals. A 24V power supply is recommended for maximum output power.Speaker OUT terminals. Ensure proper polarity for optimal sound quality.While the XH-M544 is not directly programmable, it can be used with an Arduino UNO to control audio playback. Below is an example of using an Arduino to control an audio source via a relay:
/*
Example: Controlling Audio Playback with Arduino and XH-M544
This code demonstrates how to use an Arduino to toggle an audio source
connected to the XH-M544 amplifier using a relay module.
*/
const int relayPin = 7; // Pin connected to the relay module
void setup() {
pinMode(relayPin, OUTPUT); // Set relay pin as output
digitalWrite(relayPin, LOW); // Ensure relay is off at startup
}
void loop() {
// Turn on the audio source
digitalWrite(relayPin, HIGH);
delay(10000); // Play audio for 10 seconds
// Turn off the audio source
digitalWrite(relayPin, LOW);
delay(5000); // Pause for 5 seconds
}
Note: This example assumes the audio source is connected to the XH-M544 via AUX or RCA input, and the relay module is used to control power to the audio source.
| Issue | Possible Cause | Solution |
|---|---|---|
| No sound output | Incorrect wiring or loose connections | Verify all connections and wiring. |
| Distorted audio | Overdriven input signal or low voltage | Reduce input volume or check power supply. |
| Amplifier overheating | Insufficient cooling | Add a heatsink or improve ventilation. |
| Low volume output | Low input signal or incorrect settings | Increase input volume or adjust the knob. |
| Noise or hum in audio | Poor power supply or ground loop | Use a regulated power supply and proper grounding. |
