SD Card Module

SD Card Memory Shield Module SPI  SD Adapter For Arduino

Features:

The module (SD Card Adapter) is a SD card reader module, and the SPI interface via the file system driver, microcontroller system to complete the MicroSD card read and write files.
Arduino users can directly use the Arduino IDE comes with an SD card to complete the library card initialization and read-write

Module features are as follows:

Support Micro SD Card (<=2G), Micro SDHC card (<=32G) (high-speed card)
The level conversion circuit board that can interface level is 5V or 3.3V
Power supply is 4.5V ~ 5.5V, 3.3V voltage regulator circuit board
Communication interface is a standard SPI interface


Control Interface:
A total of six pins (GND, VCC, MISO, MOSI, SCK, CS), GND to ground, VCC is the power supply, MISO, MOSI, SCK is the SPI bus, CS is the chip select signal pin

3.3V regulator circuit:
LDO AMS1117 3.3V regulator output 3.3V as level converter chip, SD card supply


SD card into the direction of signals into 3.3V, MicroSD card toward the direction of the control interface MISO signal is also converted to 3.3V, general AVR microcontroller system can read the signal
SD card connector:
Since the bomb deck for easy card insertion and removal.

 the module is easy to install positioning, to achieve inter-module combination

Package included:

1 x SD card module
