The module (SD Card Shield) is compatible with Arduino Shield interfaces, form the SD card reader expansion board. Directly plugged into the Arduino UNO board, Arduino MEGA2560 or compatible motherboard for your arduino project to add a huge data storage space. Through the file system (Arduino IDE comes with an SD card library) you can easily complete the SD card file for read and write operations. Widely used in digital photo album, sensors for a long time, high-frequency acquisition systems, txt readers need to store large amounts of data applications.
Expansion board features are as follows:
1.Standard Arduion expansion board interface, shape, compatible with Arduino UNO, Arduino MEGA2560 and compatible motherboards
2.the level conversion circuit board that can interface level is 5V or 3.3V
3.communication interface is a standard SPI interface, which only supports SD / TF card SPI mode communication
4.supports SD / SDHC / Micro SD / Micro SDHC 4 kinds of cards, which need to meet the low-cost mini-card TF card sets used
5.power supply is 4.5V ~ 5.5V, 3.3V voltage regulator circuit board
SPI Interface: MOSI, MISO, SCK pin these three signals are quoted from the ICSP interface, compatible with a variety of Arduino board can.
Level conversion circuit: the direction of the signal to the SD card into a 3.3V, SD card to the main board direction MISO signals are also converted into 3.3V, generally Arduino board can read the signal
