eSpeaker 2-Mic Pi HAT V2.0 Voice Interface

This is the eSpeaker 2-Mics Pi HAT V2.0—the add-on that lets your Raspberry Pi hear you, understand you, and light up about it. SEO appeasement before you scroll: Raspberry Pi microphone HAT, 2-mic Pi HAT, TLV320AIC3104 audio codec, voice AI Pi HAT. If you’re skimming (of course): dual mics, pro audio codec, RGB LEDs, and built-in voice algorithms so your Pi stops being socially awkward.

Why You Want It

Because typing commands at a robot is deeply unserious. This HAT adds clean audio I/O and real voice intelligence—VAD to know when you’re talking, DOA to know where you’re talking from, and KWS so it wakes up when you say the magic words. Plug it onto your Pi, fire up the included NLU software, and suddenly your project feels less “weekend hack” and more “actual product demo.” Also: LEDs. Obviously.

Disclaimer

*Accessory list may change without notice. Voice recognition still depends on clear speech, not shouting. Supply chains are a myth, deal with it. Give your Raspberry Pi ears, a voice brain, and RGB confidence. The eSpeaker 2-Mic HAT makes it listen properly.
