VS1053 - Module pinout description

Post by Victoria Nope » Mon Nov 16, 2020 11:45 pm

Hello,

here is the VS1053 module pinout description:

Image

5V - 5V power line
GND - ground power line
CS - SD card chip selector
MISO - SPI bus MISO signal common for the VS1053 chip and the SD card
SI - SPI bus MOSI signal common for the VS1053 chip and the SD card
SCK - SPI bus CLK signal common for the VS1053 chip and the SD card
XCS - VS1053 chip selector for command interface
XRESET - VS1053 chip asynchronous reset
XDCS - VS1053 chip selector for data interface
DREQ - VS1053 chip data request signal

So from the above you can see that this module uses common SPI bus for the VS1053 chip and the SD card. As a downside of this connection, the VS1053 chip communication will be disrupted by the card initialization when it's inserted or removed. For more details about this downside see this post.

Hope this helps somebody.
Cheers
