Using the SPI Flash SD Card breakout with CircuitPython is as simple as wiring it up to a microcontroller and using the Adafruit CircuitPython SD library.
It is not recommended to use this with Raspberry Pi and other single-board computers as you already have a full filesystem available to you.
Wire up your SPI Flash SD Card breakout as shown below. This example shows a Feather M4 wired up using SPI.
- Board 3V to breakout VIN
- Board GND to breakout GND
- Board SCK to breakout SCK
- Board MI(SO) to breakout MISO
- Board MO(SI) to breakout MOSI
- Board D5 to breakout CS
