Wireless Bluetooth Amp Board 100W

This amplifier board uses ABS casing and copper conductive paths for robust construction and consistent electrical performance. Its physical dimensions match standard DIY audio module footprints (refer to product image), and total weight is approximately 350g — light enough for wall-mounted or portable speaker builds. Designed for 100W speaker load handling, it incorporates a dedicated heatsink and pre-installed thermal silicone sticker to ensure thermal continuity between chip and heatsink surface. It features native Bluetooth 5.0 support for fast pairing and minimal audio delay, alongside auxiliary 3.5mm input, USB flash drive playback (FAT32 formatted), and direct line-in — giving users flexibility across modern and legacy sources. Physical controls consist of three high-quality rotary knobs for intuitive, real-time treble, bass, and volume adjustment — no firmware updates or driver installations needed. Engineered as a practical upgrade path, it replaces outdated or noisy amplifier modules in home-built speakers, studio monitors, or repurposed furniture audio systems. Package contains full mechanical assembly kit: upper and lower plates, four M2 copper posts (M2x4+3), eight M2x3 screws, four M2x18 screws, four knobs, DC adapter, heatsink, and thermal pad.
