The Raspberry Pi Pico is a very capable device, but it lacks the ability to store sizable amounts of data on the board. This is a useful function when using the Pico for tasks such as data logging. To make this function practical we can use an SD card for expanding storage via an adapter. SD cards are great for storing logging and data from microcontroller projects that can then be read on a computer. We can use SD cards in Serial Peripheral (SPI) mode which allows us to rely on easy-to-use SPI peripherals and libraries for communication. SPI mode is perfect if we’re writing short amounts of data to a file (e.g., event logging).
