Key benefits Uses the TPA3116 amplifier to deliver efficient, clear audio performance in a compact module. Resistors are precision chip resistors that help achieve a good signaltonoise ratio across the whole system. Electrolytic capacitors use fewer capacitors for stable performance. PCBs are built for reliability: 1.6 mm thick doublesided board, 2.0 ounces copper thickness, tinsprayed finish to support both large and small currents with dependable pass characteristics. What this means for you Reliable audio amplification with a compact footprint suitable for compact stereo projects, powered speakers, or DIY amplifier builds. Durable construction and materials chosen to maintain performance under a range of operating conditions. Clear signal handling from input to output, thanks to precision components and a robust PCB design. Specifications and construction details Amplifier: TPA3116 Resistors: precision chip resistors to optimize signaltonoise ratio across the system Electrolytic capacitors: fewer capacitors PCB: 1.6 mm thick doublesided board Copper: 2.0 ounces copper thickness Finish: tinsprayed full process to ensure good passing performance for large and small currents Applications and use scenarios Home audio DIY projects: integrate this module into a bookshelf speaker or compact desktop stereo to achieve clear, efficient amplification in a small enclosure. Custom powered speaker builds: use as the main amplification module in small, selfcontained speaker systems where space is limited and reliable current handling is required.
