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


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.

User comment (translated): It is possible to feed this module 5V as power supply, however it is not compatible with 5 Volt logic.

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