## Description

The Adafruit microSD Card BFF Add-On slots onto the back of any QT Py or Xiao board, adding a microSD card slot for megabytes or gigabytes of file storage. Using the SPI bus (MOSI/MISO/SCK) plus one chip select pin, you can read and write files for data logging, audio playback, image storage, and more. The BFF ("Best Friend Forever") PCB is designed to match the QT Py/Xiao footprint exactly. Solder it directly for a permanent, ultra-compact stack, or use pin and socket headers to make it removable. Since the QT Py already operates at 3.3V, no level shifter or regulator is needed.
