Secure Digital, or SD, cards and tiny microSD cards are inexpensive and ubiquituous means of adding lots of storage to devices. For a few dollars you can have gigabytes of storage at your fingertips (smaller than your fingertips actually!). With small MicroPython boards you typically have a very limited amount of flash memory to store code and data. Wouldn’t it be nice if you could connect a microSD card to a MicroPython board and expand its storage? It turns you can use microSD cards with MicroPython! In fact some boards like the pyboard come with microSD card support built-in, and for other boards like the ESP8266 they can easily be connected to a microSD card that expands their storage.
This guide explores how to use a microSD card as the root filesystem for a MicroPython board. Specifically adding a microSD card to the pyboard, WiPy, and ESP8266 will be covered in this guide. You’ll learn how to connect a microSD card to the board and mount it as a new root filesystem that MicroPython can use to store code & data just like its internal filesystem.

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.
