Part # AFSDR-FS-523
The F40 (ALFAT) SDR (SD-Reader) board is specifically designed to highlight F40's (ALFAT) SD-Reader mode. In this mode, F40 still accepts commands to access files on the SD card but it can also become an SD card reader, making this an ideal solution for data logging applications. The pinouts of both the F40 (ALFAT) SDR board and the F40 (ALFAT) OEM board are compatible making both boards interchangeable. They even have the same footprint and mounting layout.
This board is also the reference design for developers intergrating F40 into their existing product and utilizing the SD-Reader mode.
