The reader module of the memory micro SD card with goldpin connectors - 2.54 mm pitch for self-soldering. It communicates with main board via SPI or SDIO interface. It works with a voltage of 3.3 V.
The SD cards communicate using the SPI bus. Most of the microcontrollers, including those used in Arduino AVRy, have hardware control over this interface.
The product is compatible with STM32
The manufacturer has prepared a user guide along with a sample program for the STM32.
Supply voltage: 3.3 V
- Interface: SPI
