Description M5Stack ATOMIC TF-Card Reader is a compact TF card read/write module for ATOM series hosts. This reader uses a self-ejecting microSD card slot and supports TF cards up to 16GB with FAT/FAT32 format. The MicroSD reader module helps store configuration files, user data, logs, and external resources without occupying valuable host Flash space. Designed for Atom-Matrix, Atom-Lite, ATOMS3, and AtomS3-Lite, the module gives ATOM projects a simple removable storage interface. During program execution, files on the TF card can be accessed when needed, making the reader useful for data logging, parameter loading, and file read/write workflows. The MicroSD reader module is suitable for embedded control systems, industrial automation, and IoT devices that need compact local storage.
