Introduction:
SD card to PCIe Add-on card adapter design for both high speed SD3.0/SDXC/UHS-I cards and SDIO2.0/IO1.8V cards by selecting on-board EEPROMs by slide switch.
Besides, as 1.8V LDO is on board, not only 3.3V but also 1.8V can be applied to SD Card power by jumper.

Notice
- To use SD / SDHC/ SDXC Cards on Windows XP/VISTA/7 your system requires install RICOH private driver for more compatibility (download here). Otherwise your SD cards can’t work properly.
- To use SD / SDHC / SDXC Memory Card Formatting Software, Please download file from SDCARD.org web-site as below:
https://www.sdcard.org/downloads/formatter_4/
Please backup your data before using the formatting program.
- SDIO 2.0/IO=1.8V mode is for special usage for such as testing SDIO WiFi card with 1.8V I/O signaling.
So, when SW1=2-3, normal SD card cannot be recognized.
For normal SD cards of SDIO2.0 or SD2.0 with 3.3V I/O signaling, please purchase MP230.
System Requirements:
- PCI-E slot
