NEW GUIDE: Adafruit SPI Flash SD Card #AdafruitLearningSystem #Adafruit @adafruit
Looks like SPI flash, but it’s secretly an SD card!
This breakout is for a fascinating chip – it looks like an SPI Flash storage chip (like the GD25Q16) but its really an SD card, in an SMT chip format. What that means is that you wire up like an SD card breakout, and use the SD card libraries you already have for your microcontroller. For example, you can use the built in SD library in Arduino, or for CircuitPython we have an sdcard library. The breakout will act just like a 512 MB sized card with FAT formatting (it’s pre-formatted).
The Adafruit SPI Flash SD Card guide has everything you need to get started with this breakout. There’s an overview and info on pinouts. Because it works with the current SD Card libraries for Arduino and CircuitPython, the Arduino and CircuitPython pages show you how to wire it up to your project, and then link you to the existing guides for using an SD card with each language. Finally, there’s a downloads page with resources.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
