Micro SD Data Logger Module with RTC

This datalogger module is excellent for writing data with a timestamp to an SD card. During a power interruption, the time is saved from the RTC to a backup battery (time continues to run). The RTC is controlled via the I2C bus (SDA and SCL pins). There is already a ready-made Arduino library for controlling the module, which you can find in the Library Manager under "DS1307RTC".  The memory card is accessed via the SPI connection (CS, MOSI, MISO, and SCK pins). Here you can use a ready-made Arduino library: "SD Library". There are also alternative libraries that work very well. The only thing you need to adjust in the library is the CS pin. Normally, pin 4 is used here. However, you can also change it to pin 10.
