SD Card Shield For Arduino

SD Card Shield is compatible with the Arduino Shield interface and forms an SD card read / write expansion board. Insert directly into the arduino UNO motherboard, the arduino MEGA2560 or its compatible motherboard adds a lot of data storage space to your arduino project. Through the file system (arduino IDE comes with SD card library) can be easily done 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 a large amount of data.
Expansion board features are as follows:
1. Standard Arduion expansion board interface, shape, compatible arduino UNO, arduino MEGA2560 and its compatible motherboard
2. On-board level conversion circuit, the interface level can be 5V or 3.3V
3. Standard SPI interface communication interface, only supports SD / TF card SPI mode communication
4 support SD / SDHC / Micro SD / Micro SDHC four kinds of cards, including the need to use low-cost TF card micro-card
5. The power supply is 4.5V ~ 5.5V, 3.3V voltage regulator circuit board
