SdFat is a C++ library for Arduino and other embedded platforms providing access to SD cards with FAT16/FAT32/exFAT filesystems. It supports SPI and SDIO interfaces, UTF-8 filenames, and high-performance read/write operations.
Use cases
- read and write files on an SD card from Arduino
- access exFAT formatted SD cards on microcontrollers
- log sensor data to SD card
- use SDIO mode on RP2040/RP2350 for fast SD card access
- support UTF-8 filenames on embedded filesystems
When to choose
- you need FAT16/FAT32/exFAT support on Arduino or RP2040-class hardware
- you need high SD card throughput such as SDIO on Raspberry Pi Pico
- you need Unicode/UTF-8 filenames on embedded devices
When to avoid
- you are not on an embedded/microcontroller platform
- you need a filesystem other than FAT variants
- your board lacks SPI or SDIO support for SD cards
