Mono 100W Bluetooth Audio Amplifier Board Module (Model: 1001B, TPA3116D2, Bluetooth 5.1) Key benefits Clean, powerful mono output: Delivers up to 100W mono amplification for a single speaker or subwoofer channel, giving clear, level sound where a singlechannel solution is required. Reliable wireless connectivity: Builtin Bluetooth 5.1 provides stable, lowlatency streaming from modern smartphones, tablets, and Bluetoothenabled sources. Efficient amplification: Powered by the TPA3116D2 amplifier chip, the board offers efficient Class D performance that reduces heat and improves energy usage compared with traditional linear amps. Easy integration: Compact board format and standard PCB construction make it simple to mount in DIY speaker projects, retrofit applications, or custom audio enclosures. What this module does for you Converts a Bluetooth audio source into a power mono output suitable for driving a single speaker or subwoofer without needing external amplification. Reduces system complexity by combining wireless input and amplification on one board, saving space and simplifying wiring. Supports reliable, longrange pairing with Bluetooth 5.1compatible devices for consistent streaming in home, studio, or small venue settings. Important attributes Model: 1001B Power amplifier chip: TPA3116D2 Product name: Mono 100W Bluetooth audio amplifier board module Bluetooth version: 5.1 Function: Bluetooth audio reception and mono power amplification Form factor: Compact amplifier board designed for integration into speaker systems and DIY projects Material and construction: Standard PCB assembly suitable for mounting inside audio enclosures (boardlevel module) Compatibility Works with Bluetooth 5.1 and earlier Bluetooth audio devices (smartphones, tablets, laptops, Bluetooth transmitters). Intended for use with appropriate speaker loads and compatible power supplies; integrate with common speaker and enclosure types used in DIY and professional audio builds. Practical use scenarios 1) DIY powered subwoofer: Use the module to add a dedicated 100W mono sub channel to a bookshelf or floorstanding speaker system for stronger lowfrequency performance. 2) Singlechannel PA or announcement system: Drive a single speaker in small publicaddress applications where clear, powerful mono output is required. 3) Custom audio projects and restorations: Retrofit into vintage cabinetry or custom enclosures to provide modern Bluetooth streaming and efficient amplification without replacing existing speaker hardware. Safety and installation notes Designed as a boardlevel module for integration by users familiar with audio electronics. Ensure correct speaker impedance and a suitable power supply when installing. Provide adequate ventilation and secure mounting inside enclosures to maintain reliable operation. details Model: 1001B Includes: Mono 100W Bluetooth audio amplifier board module with TPA3116D2 and Bluetooth 5.1 functionality For integration or technical questions, refer to your system requirements and consult a qualified technician when needed.
