# eMMC & SD-Card

The Kumquat features an SDIO interface accessible through a 2x10 1.27mm Pin Header. This interface is primarily intended for connecting storage devices such as SD cards or eMMC modules to the Kumquat. However, users also have the flexibility to utilize this interface for custom solutions. The following document outlines the pinout details of the SDIO Interface.
