ESP32-S3-BOX-3

The S3-BOX-3 is what it looks like when a silicon vendor takes open seriously: a complete voice-assistant dev kit — dual mics, speaker, touch LCD, battery-capable — with schematics, firmware, and the offline speech-recognition stack all published. It runs Espressif’s on-device wake word and command recognition with no cloud at all, and the ESP-IDF examples take you from unboxing to a working custom assistant in an afternoon.
