XH-M120 PAM8610 Amplifier Board Pinout Explanation and Connection Guide
The XH-M120 PAM8610 Amplifier Board is a compact and efficient audio amplifier module designed for various IoT applications. This documentation provides a detailed explanation of each pin on the board, along with a step-by-step connection guide.
Pinout:
The XH-M120 PAM8610 Amplifier Board has a total of 12 pins, arranged in two rows of 6 pins each. The pinout is as follows:
Row 1:
1. VIN: Input voltage pin (DC 5V-12V). This pin supplies power to the amplifier board.
2. GND: Ground pin. This pin connects to the negative terminal of the power source and provides a common ground reference.
3. BCLK: I2S clock input pin. This pin is used to clock the I2S data signal.
4. DIN: I2S data input pin. This pin receives the audio data signal.
5. L_OUT: Left channel audio output pin. This pin provides the amplified audio signal for the left channel.
6. R_OUT: Right channel audio output pin. This pin provides the amplified audio signal for the right channel.
Row 2:
1. SDA: I2C data pin. This pin is used for I2C communication with external devices (optional).
2. SCL: I2C clock pin. This pin is used to clock the I2C data signal (optional).
3. shutdown: Shutdown pin (active low). This pin can be connected to a digital signal to shut down the amplifier (optional).
4. mute: Mute pin (active low). This pin can be connected to a digital signal to mute the amplifier (optional).
5. GAIN: Gain control pin. This pin can be connected to a potentiometer or a digital signal to adjust the amplifier gain.
6. NC: No connection ( reserved for future use).
Connection Guide:
To connect the XH-M120 PAM8610 Amplifier Board, follow these steps:
Step 1: Power Connection
Connect the VIN pin to a DC power source (5V-12V) using a suitable power cable or connector.
Connect the GND pin to the negative terminal of the power source and a common ground reference point.
Step 2: Audio Input
Connect the BCLK pin to the I2S clock output of your audio source (e.g., microcontroller or audio codec).
Connect the DIN pin to the I2S data output of your audio source.
Step 3: Audio Output
Connect the L_OUT pin to the left channel audio output of your speaker or audio device.
Connect the R_OUT pin to the right channel audio output of your speaker or audio device.
Optional Connections:
If using I2C communication, connect the SDA pin to the I2C data pin of your I2C master device.
If using I2C communication, connect the SCL pin to the I2C clock pin of your I2C master device.
If using shutdown functionality, connect the shutdown pin to a digital signal that can be used to shut down the amplifier.
If using mute functionality, connect the mute pin to a digital signal that can be used to mute the amplifier.
If using gain control, connect the GAIN pin to a potentiometer or digital signal that can adjust the amplifier gain.
Note:
Ensure correct polarity and voltage ratings when making connections to avoid damage to the board or other components.
Use suitable connectors, cables, and wiring to minimize noise and interference.
