Offline Intelligent Voice Recognition Module Public Version Test Dual-Microphone Noise Reduction Control Recognition Popis

Power supply voltage VBAT ranges from 3.6V to 5.5V.
Built-in 3-channel high-performance LDO circuitry, requiring no external power supply chip and only a few external resistors.
High-performance 32-bit CPU, supporting to 220MHz operating frequency.
Built-in 640KB and 512-bit EFUSE processor (BNPUV3.5).
High-performance voice recognition, voiceprint recognition, command word self-learning, voice detection, trial learning functions, and voice noise reduction.

The product features a built-in high-performance, low-power AUDIO CODEC module, supporting single-channel ADC sampling and single-channel DAC playback. It supports AUTOMATIC LEVEL CONTROL (LAC function) and various sampling rates including 8kHz, 16kHz, 24kHz, 32kHz, 44.1kHz, and 48kHz. Additionally, it supports one IIS audio expansion path and one PDM interface, which can connect to one or two data MEMS microphones. The ambient operating temperature ranges from -40C to +85C, while the storage temperature ranges from -55C to +150C.
