Micro SD Board

Micro SD Card Module
SPI interface via file system driver, microcontroller system to complete the MicroSD card reading and writing functions
Arduino users can use Arduino IDE comes with an SD card to complete the library
Card initialization and read-write directly
Power supply:4.5V ~ 5.5V, 3.3V voltage regulator circuit board
Communication interface: a standard SPI interface
Supply voltage: 4.5V(min), 5V(typical), 5.5V(max)
Current: 0.2mA(min), 80mA(typical), 200mA(max)
Level conversion circuit board can interface: 5V or 3.3V
Card supported: Micro SD card (< =2G)，Mirco SDHC card (< =32G)
Size: approx. 42 x 24 x 12mm
Weight: approx. 5g

Control Interface: Six pins (GND, VCC, MISO, MOSI, SCK, CS), GND to ground, VCC is power supply, MISO, MOSI, SCK is SPI bus, CS is chip selecting signal pin
3.3V voltage regulator circuit: LDO regulator output 3.3V
Level conversion circuit: signal of Micro SD card direction into 3.3V, MISO signal which controls interface direction is also converted to 3.3V. general AVR microcontroller system can read the signal
Micro SD card connector: self-spring socket, easy to insertion and removal card
Positioning holes: 4pcs 2mm diameter M2 screws hole, good for installing positioning, to achieve inter-module combination
