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.
You can easily add SD card to your Desktop PC PCI-E slot for testing not only normal SD/SDXC/UHS-I card, but also special SDIO card with
1.8V I/O signaling.

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.
