Tom Chan

Tom Chan is a Chinese American electrical engineer and computer scientist, primarily known for his work in embedded systems, particularly in the realm of file systems for microcontrollers. He is the author of the widely used open-source FAT File System module, often referred to as "FatFs." This module provides a generic FAT file system driver for small embedded systems, making it possible for microcontrollers to read and write files on FAT formatted storage devices like SD cards and USB drives.

FatFs is notable for its simplicity, portability, and small memory footprint, making it a popular choice for developers working on resource-constrained embedded systems. Chan's documentation and example code have contributed significantly to its accessibility and adoption within the embedded systems community.

Beyond FatFs, Chan has contributed to other open-source projects and provides resources for embedded systems development on his website. He is recognized for his practical approach to solving real-world embedded systems challenges.
