SPI Reader Micro SD Memory Card TF Memory Card Shield Module for Arduino

Support mini SD card (less than equal 2G), mini SDHC card (less than equal 32 G) (high-speed card).
The level conversion circuit board, the level interface can 5V or 3.3V.
Power Supply 4.5V ~ 5.5V, 3.3V voltage regulator board.
Communication interface is a standard SPI interface.
Color: As shown
Size: 4.1x 2.4cm
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 3.3 V level converter chip, mini SD card supply.
A level conversion circuit:
mini SD card in the direction of the signals in 3.3 V, the miniSD card in the direction of the control interface MISO converted signal also 3.3V, can universal AVR minicontroller system read the signal.
mini SD card port:
Since the bomb deck for easy card insertion and removal.
positioning holes:
4 M2 screws positioning hole diameter of 2.2 mm, the module is easy to install positioning in order to achieve inter-module combination.
