XD-204 UNO Data Logger Module Logging Recorder Shield Arduino SD Card Reader
– SD card interface with FAT16 or FAT32 paper size.
– 3.3 v circuit level converter to avoid damaging the SD card
– Real-time clock (RTC) keeps time, even when Arduino is disconnected.
– Years of replacement batteries
– Including the SD card and the RTC library and the sample code means that you can get fast
– Welded joint, circuit area or prototype design sensor.
– Built-in 3.3V reference voltage regulator is a reliable and can be reliably run, which require a lot of power to run the SD card
