Adafruit CircuitPython Module Install

To use a microSD card with your Adafruit CircuitPython board you'll need to install

the Adafruit_CircuitPython_SD module on your board.

First make sure you are running the latest version of Adafruit CircuitPython for your board.

Next you'll need to install the necessary libraries to use the hardware--carefully follow the steps to find and install these

libraries from Adafruit's CircuitPython library bundle. Our introduction guide has a great page on how to install the

library bundle for both express and non-express boards. Be sure to use the latest CircuitPython Bundle as it includes

an updated version of the SD card module with a few necessary fixes!

Remember for non-express boards like the, you'll need to manually install the necessary libraries from the bundle:

adafruit_sdcard.mpy

adafruit_bus_device

If your board doesn't support USB mass storage, like the ESP8266, then use a tool like ampy to copy the file to the

board. You can use the latest version of ampy and its new directory copy command to easily move module directories

to the board.

Before continuing make sure your board's lib folder or root filesystem has the adafruit_sdcard.mpy and

adafruit_bus_device modules copied over.

Usage

The following section will show how to initialize the SD card and read & write data to it from the board's Python prompt

/ REPL.
