Add SD card storage to your next project with this simple, through-hole SD/MMC socket. SD and MMC cards communicate over an SPI serial bus (as well as a 4-bit proprietary bus), making them easy to interface with microcontrollers like Arduino, PIC, and many others — ideal for data logging, audio playback, and file storage applications.
Key Features
- SD & MMC Compatible – Works with both Secure Digital and MultiMedia Card formats
- SPI Interface – Simple serial bus protocol, widely supported by microcontroller libraries
- Through-Hole Design – Easy to solder onto a custom PCB or prototyping board
Ideal For
- Data logging projects requiring large storage capacity
- Adding file system storage to Arduino, PIC, or similar microcontroller projects
- Audio and media playback applications
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
