Product Description:
1.Support Micro SD card, micro SDHC card
2.Interface level: 5V or 3.3V
3.Powr supply: 4.5V to 5.5V , 3.3V voltage regulator circuit board
4.Currency: 0.2-200mA
5.Size:4.20*2.40*0.5 (About 1.65inch X 0.94inch X 0.2inch)
6.Communication interface: SPI
7.With 4 holes for M2 screw , it is easy to install
8.The module (MicroSD Card Adapter) is a Micro SD card reading and writing module.
9.Through the file system and SPI interface driver, the MCU system can complete
10.the reading and writing of files in the MicroSD card. Arduino users can directly
11.use the SD card library that comes with the Arduino IDE to initialize and read the card.
12.Control interface: a total of 6 pins (GND, VCC, MISO, MOSI, SCK, CS), GND is ground,VCC is the power supply, MISO, MOSI, SCK is the SPI bus, CS is the chip select signal pin;
14.3.3V voltage regulator circuit: 3.3V of LDO regulated output is level conversion chip, Micro SD card power supply;
15.Level shifting circuit: The signal to the direction of the Micro SD card is converted to 3.3V
and the MISO signal of the MicroSD card to the control interface is also converted to 3.3V.
16.Generally, the AVR microcontroller system can read the signal;
17.Micro SD card holder: It is a self elastic card holder for easy insertion and removal of cards.

Interface parameters:
Minimum value VCC 4.5V/0.2mA
Typical value VCC 5V/80mA
Maximum value VCC 5.5V/200mA

Package Included:
10 X micro sd card module
