Highlights
- As a WAV player module, it is based on 12bit DA converter chip MCP4921. With SD card, it can complete mono playing, with a sampling rate below 22.1K, way format file below16-bit. It is characteristic of low SNR. When working at low volume, it gives out big noise, so we should adjust the volume to a half circle above. If we use external power amplifier, it works better. We can adjust the volume on the amplifier, especially for some places without requirement for sound quality, such as subway, ATM machine, electronic clock and other destinations with sound prompts.
