The following is the SD card reader wiring:

Number Pin Label Description
15 SD_CS SD card reader: chip select signal, low level enable
16 SD_MOSI SD card reader: SPI bus input
17 SD_MISO SD card reader: SPI bus output
18 SD_SCK SD card reader: SPI bus clock signal

Schema

The schema of the module

Power supply

The module can be used with 5V or 3.3V supply:

  • for 5 Volt supply, the J1 should be open, and the XC6206 should be in place on the board. This is the configuration when the module leaves the factory.
  • for 3.3V supply, the J1 should be closed, and the power regulator circuit XC6202 can be removed.

The signals controlling the module should always be 3.3V levels, independent of the power supply choice!
