What is difference between SD and SDIO?
The SD standard offers great flexibility, include the ability to use the SD slot for more than memory cards. SDIO card is an interface that extends the functionality of devices by using a standard SD card slot to give devices new capabilities.
What is the difference between SPI and SDIO?
The SD protocol uses separate lines for commands and data, whereas SPI uses a single wire pair for both. So, in some situations, 1-bit SDIO may be a little faster than SPI, as it’s possible to send commands concurrently with data.

What is SDIO ESP32?
Description. This ESP32 Board comes with Additional SDIO interface pins (SDO, SDI, and CLK). SDIO interface can be used for interfacing external memory cards for data logging applications and many other applications where high speed serial data communication is needed.
Is TF card same as SD?
Although SD cards are the most popular standard, they are bulky. TF cards were developed to be smaller and more compact than SD cards while also preserving the functionality of SD cards. This means you can use a TF memory card in your digital camera or any gadget that uses an SD card using an SD card adapter.
