Description

Overview

WT2605 has ADC and DAC peripherals with high signal-to-noise ratio, and the resolution is as high as 16bit.

At the same time, it has standard UART, key control and other functions, and can store audio files by external USB flash, TF card, SPI Flash, etc.

SPI Flash supports file management, and can realize file index playback, file name playback and other functions. Support standard MP3, WAV audio file playback and Bluetooth playback, and also decode and play audio files such as APE and FLAC (to be customized). Please refer to the scheme specification and schematic diagram for details.
