I found a MicroSD card reader module working with SPI. Is it possible to connect it to Raspberry Pi Zero W via GPIO?

Module scheme

EDIT: The module can also be connected via SDIO pins. Which of these two methods (SPI or SDIO) would get the most performance for card reader?

Here is SDIO pinout at Raspberry Pi end:

To answer you question about performance, SDIO will get you better performance over SPI.

You can enable your SPI configuration through #sudo raspi-config and then wire it with your Pi Zero W. You can look up more via this post, is this what you're looking for ?

How can I wire this SD card reader to RaspberryPi?

  • I saw this post earlier, but the pins description on the module that I have is more related to SDIO than SPI. The only problem is that I cannot find which pins in Raspberry Pi Zero W are intended for SDIO.
