Features

• TDA7379 Stereo Amplifier Board designed for compact two-channel audio amplification.
• This is a stereo amplifier, not a mono amplifier.
• Provides separate Left (L) and Right (R) audio channels for stereo sound.
• Two compatible speakers can be connected simultaneously—one speaker to the Left channel and another speaker to the Right channel.
• The product image shows a single speaker connection only as an example; the board supports both L + R speaker outputs.
• Delivers a claimed output capability of 38W + 38W under suitable operating conditions.
• Wide DC input range of approximately 9V to 17.5V.
• DC 12V is a practical supply voltage for many applications.
• Uses the TDA7379 / CD7379 audio power amplifier IC.
• Compact PCB size of approximately 33.3 × 25mm, making it suitable for space-limited projects.
• Suitable for DIY speakers, portable audio systems, custom speaker boxes and other audio projects.
• TDA7379 supports stereo dual-channel operation and is specified for up to 38W × 2 at 4Ω under its rated test conditions.
• The IC includes features such as thermal protection and short-circuit protection.
• Small PCB design makes it convenient for integrating into custom audio equipment.
• Can be paired with suitable Bluetooth, MP3 decoder, DAC or other analog audio source modules.
• The TDA7379 Stereo Amplifier Board is a compact dual-channel audio power amplifier module designed for building small and medium DIY audio systems. Based on the TDA7379 / CD7379 amplifier IC, this board provides separate Left (L) and Right (R) audio channels, allowing it to operate as a true stereo amplifier rather than a single-channel mono amplifier.
• One important point about this product is that both Left and Right channels can be used simultaneously. Although the supplied product image shows only one speaker connected as an example, the board is designed for two-channel stereo operation. You can connect one compatible speaker to the Left channel and another compatible speaker to the Right channel to create a proper L/R stereo speaker system.
• The TDA7379 IC is specified by STMicroelectronics as a Class AB audio amplifier capable of operating in a dual-bridge configuration. Its published specifications include up to 38W × 2 at 4Ω under specified test conditions, making it suitable for compact high-power audio applications.
• The board accepts a DC 9V to 17.5V power supply, with 12V being a commonly useful operating voltage for this type of module. The wide input range gives flexibility for different DIY audio projects, although the actual achievable output power will depend heavily on the selected supply voltage and available current.
• The Left and Right audio inputs allow the module to receive a standard stereo audio signal. It can therefore be connected to compatible audio sources such as Bluetooth receiver modules, MP3 decoder boards, DAC modules, computer audio outputs, mobile-device audio interfaces or other suitable line-level sources.
• For the speaker side, the amplifier provides separate output channels. A typical stereo setup consists of:
• Audio Input: L + R + GND
  Speaker Output: Left Speaker + Right Speaker
  Power Input: DC Positive + DC Negative
• This means users do not need to combine the Left and Right audio signals into one mono channel when stereo sound is desired. Instead, the Left signal should drive the Left speaker and the Right signal should drive the Right speaker.
• The board is extremely compact, with the supplied product dimensions showing approximately 33.3mm × 25mm. This small footprint makes it particularly useful for custom speaker boxes, portable audio projects, compact amplifier builds and other applications where PCB space is limited.
• The TDA7379 is a well-known audio power amplifier IC with integrated protection features. Published component information lists thermal protection and short-circuit protection, which can help protect the amplifier under certain fault conditions.
• The claimed 38W + 38W output should be understood in relation to the power supply, speaker impedance, distortion level and thermal conditions. The 38W × 2 figure is associated with specific test conditions, including a 4Ω load, rather than meaning that the tiny PCB will continuously deliver 76W under every real-world condition.
• Because higher output power generates significant heat, proper cooling is important, especially when operating near the upper end of the module’s output capability. A suitable heatsink should be used on the amplifier IC when required, and the final enclosure should provide sufficient airflow.
• The TDA7379 Stereo Amplifier Board is therefore an excellent compact solution for users who need a small Left + Right dual-channel amplifier for DIY speaker systems. It can be used for portable speakers, custom stereo boxes, small multimedia audio systems, car-audio projects, Bluetooth speaker builds and various electronics experiments.
• Note: Actual output power depends on supply voltage, speaker impedance, audio signal, distortion level, power supply capability and cooling. The 38W + 38W figure is a maximum/nominal specification under suitable conditions rather than a guaranteed continuous output in every setup.
• Stereo Connection Clarification
• This module is Stereo — not Mono.
• Left Channel: Connect the Left audio input and Left speaker output.
• Right Channel: Connect the Right audio input and Right speaker output.
• Power: Connect the required DC positive and negative supply.
• Important: The image showing only one speaker is simply a connection example. Both Left and Right speakers can be connected at the same time for full stereo operation.
