I would be interested in buying the AK-SDFS-UART module to add logging functionality to my project.

Is it possible to know what is the model of the microcontroller used on the logger?
What is the maximum size of the SDcard that can be used with this module?

Thank you.

Hi @alessandro.b,

The MCU it’s an STM32F103T8U6.

You can use SD and SDHC cards up to 32GB.

Thanks for the information.

Is the source-code of the firmware for the SMT32 MCU available? If yes, which module do I need to upload my modifications?

Hi @alessandro.b,

The source code for that particular product is not available.
