Hardware Introduction
The module is single-sided mounted with pins on three sides. The pin positions are basically compatible with QLIFE-ASR01M. The functional pins used by users are mainly on the pins on both sides. The middle ones are debugging and programming ports and cannot be used by users. The module supports single microphone input and can be directly connected to the module. It supports AEC echo cancellation function and has relevant audio reference signal input pins. At the same time, it supports real-person voice reply and can directly drive the speaker.
