Atomic TF-Card Reader is a module designed to read and write TF (MicroSD) cards. It is a version of the ATOM TF-CARD module that does not include a controller. Instead, it is compatible with Atom Matrix, Atom Lite, AtomS3, and AtomS3 Lite. This allows users who already have those Atom series controllers to conveniently purchase and use the Atomic TF-Card Reader.
