The module (SD Card Shield) is compatible with Shield interface, form the SD card read and write expansion board. Directly plugged into the motherboard, MEGA2560 or its compatible motherboard adds a huge amount of data storage space to your project. Through the file system IDE comes with SD card library) can be easily completed on the SD card file read and write operations. Widely used in digital photo albums, sensors for a long time, high-frequency acquisition system, txt reader and other applications need to store large amounts of data.
The expansion board features are as follows:
1. Standard Arduion expansion board interface, shape, compatible , MEGA2560 and its compatible motherboard For ArduinoS UNOR3
2. On-board level conversion circuit, the interface level can be 5V or 3.3V
3. Communication interface for the standard SPI interface, only supports SD / TF card SPI mode communication
4. Support SD / SDHC / Micr SD / Micr SDHC and other four kinds of cards, including micro-card with the need to use cheap TF card sets
5. Power supply for the 4.5V ~ 5.5V, 3.3V regulator circuit board
