1pc 5128 Amplifier Board — VS88715V Class D Mono Audio Module (3–5W / 5W) This compact mono Class D amplifier board (model VS88715V, often referenced as 5128) delivers lowdistortion audio amplification in a small, easytointegrate package. It provides 3–5W output performance with a nominal 5W capability, making it a practical choice for small speaker systems and DIY audio projects that require efficient, clean amplification. Key benefits Efficient Class D design: delivers solid audio power with low heat generation, increasing reliability in enclosed or portable builds. Low distortion: maintains clearer sound at typical listening levels compared with unfiltered, lowcost amplifier modules. Simple integration: a singlechannel module that is easy to add to custom speaker projects, electronics prototypes, and embedded systems. Compact and practical: small form factor allows mounting inside compact enclosures where space is limited. Main features and attributes Model: VS88715V (5128) Output power: 3–5W, nominal 5W performance for a single channel Channel: Mono (singlechannel output) Amplifier class: Class D digital amplifier Sound character: Designed for low distortion and efficient amplification Quantity: 1 piece per package Functionality and performance Amplifies lowlevel audio input to drive a single speaker with up to approximately 5W output power. Class D topology optimizes power efficiency and reduces heat, which helps maintain stable operation in compact enclosures. Lowdistortion design improves audio clarity for voice and music in smallscale applications. Compatibility and use Suitable for integration into DIY speaker projects, small powered speaker enclosures, and embedded audio systems. Works well with common audio sources and microcontrollerbased projects where a mono amplified output is required. Compact form factor fits tight spaces; can be mounted inside hobby enclosures or custombuilt housings. Typical applications Portable or desktop singlespeaker projects: add amplification to a compact speaker for improved volume and clarity. DIY electronics and maker projects: use with microcontrollers, MP3 players, or audio modules to produce audible output for prototypes and demonstrations. Intercoms, doorbells, and voicealert systems: provide a straightforward mono amplifier solution where space and power efficiency matter.
