If you have a project with any audio, video, graphics, data logging, etc in it, you'll find that having a removable storage option is essential. Most microcontrollers have extremely limited built-in storage. For example, even the Arduino Mega chip (the Atmega2560) has a mere 4Kbytes of EEPROM storage. There's more flash (256K) but you can't write to it as easily and you have to be careful if you want to store information in flash that you don't overwrite the program itself!

This Micro SD Card Adapter Module is a Micro SD card reader module, and the SPI interface via the file system driver, microcontroller system to complete the Micro SD 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.

FEATURES:

• Support Micro SD Card, Micro SDHC card (high-speed card)
• The level conversion circuit board that can interface level is 5V or 3.3V
• 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 regulator output 3.3V as level converter chip, Micro SD card supply
• Level conversion circuit: Micro SD card into the direction of signals into 3.3V, Micro SD card toward the direction of the control interface MISO signal is also converted to 3.3V, general AVR microcontroller system can read the signal;
• Micro SD card connector: yes since the bomb deck for easy card insertion and removal.
• Positioning holes: 4 M2 screws positioning hole diameter of 2.2mm, easy to install positioning, to achieve inter-module combination;
• Power supply: 4.5V - 5.5V, 3.3V voltage regulator circuit board
• Positioning holes: 4 M2 screws positioning hole diameter of 2.2mm
• Control Interface: GND, VCC, MISO, MOSI, SCK, CS
• Size: 45 x 28mm
