SD Card Shield For Arduino

Product Description

SD Card Shield For Arduino

The module (SD Card Shield) is compatible with Arduino Shield interface, form the SD card read and write expansion board. Directly plugged into the Arduino UNO motherboard, the Arduino MEGA2560 or its compatible motherboard adds a huge amount of data storage space to your arduino project. Through the file system (Arduino 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 Arduino UNO, Arduino MEGA2560 and its compatible motherboard

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 / Micro SD / Micro 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

SPI Interface: MOSI, MISO, SCK These three signal pins are from the ICSP interface, you can compatible with a variety of Arduino motherboard.

Level conversion circuit: the SD card to the direction of the signal is converted to 3.3V, SD card to the direction of the MISO signal board also converted into 3.3V, the general Arduino motherboard can read the signal;

Regulator circuit: LDO regulator output level of 3.3V for the conversion chip, SD card power supply;

Chip select pin: SD card CS pin connected to the Arduino motherboard D4 digital pin;

SD card socket: is a self-playing card holder, easy to plug the card, can be inserted SD card, Micro SD card inserted TF card sets
