The board ships with a small front panel that removes the need to mark and drill holes, and it pairs the TI TPA3251D2 digital amplifier architecture with quality front-stage op-amps for noticeably clear sound. For those building bookshelf or portable Bluetooth speakers, the T220HS-W delivers flexibility and power across a wide 12-36V supply range.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePanel Design:\u003c\/strong\u003e The included DIY small panel saves time when installing the module into a custom enclosure by eliminating drilling and alignment tasks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTPA3251D2 Chip:\u003c\/strong\u003e The TI TPA3251D2 HiFi amplifier chip with PurePath technology yields very low distortion and high clarity for detailed playback.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide Voltage Range:\u003c\/strong\u003e Support for 12V to 36V DC allows use with a variety of PSUs, batteries, or the supplied 36V 8A adapter for higher-power setups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMultiple Inputs:\u003c\/strong\u003e Bluetooth 5.2 plus USB and AUX inputs give flexible playback options; USB decodes WAV, FLAC, APE, and MP3 while Bluetooth supports AAC and SBC.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Precision Op-Amps:\u003c\/strong\u003e Four TI NE5532 op-amps in gold-plated sockets reduce noise and let you upgrade the front-stage op-amps if desired for tonal changes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuality Passive Components:\u003c\/strong\u003e Dedicated inductors and low-loss metal film and high-capacity capacitors lower heat and improve stability under load.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe T220HS-W is aimed at hobbyists and makers building compact 2.0 Bluetooth speakers, desktop HiFi rigs, or custom home-audio projects that need a ready-to-fit amplifier module with modern connectivity and high output capability.
