Micro SD (YS-41) Card Reader Module With SPI Interface

The module is a micro SD card reading and writing module, the file system and SPI interface driver, SCM system can complete the microSD card file to read and write. Arduino users can directly use the IDE Arduino comes with the SD card program library to complete the initialization of the card and read and write.

Features:

1. Support Micro SD card, SDHC Micro card (high speed card)
2. Board level conversion circuit, that is, the interface level can be 5V or 3.3V
3. Power supply for the 4.5V~5.5V, the board of the 3.3V regulator circuit
4. Communication interface for standard SPI interface
5. 4 M2 screw positioning holes, easy to install

Interface parameter:

Specifications:

1. Control interface: a total of 6 (GND and VCC, miso, MoSi, SCK, CS) pin and GND for VCC power supply, miso, MoSi, SCK for the SPI bus CS is the chip select signal feet;
2. 3.3V regulator circuit: LDO regulator output of 3.3V for the level conversion chip, Micro SD card power supply;
3. Level conversion circuit: the direction of the conversion of the signal to the Micro 3.3V, MicroSD card to control the direction of the interface MISO signal is converted into a 3.3V, the general AVR microcontroller system can read the signal;
4. Micro SD card is: Bomb card, card plug.
5. The positioning hole: 4 M2 screw locating hole, the aperture is 2.2mm, the module is easy to install and position, and the module is realized.

Package Include:

1. 1 X Micro SD (YS-41) Card Reader Module With SPI Interface.
