Features
The module (MicroSD Card Adapter) is a Micro SD card reader module, and the SPI interface via the file system driver, microcontroller system to complete the MicroSD card read and write files.
users can directly use the IDE comes with an SD card to complete the library card initialization and read-write
Module features are as follows
Support Micro SD Card (
The level conversion circuit board that can interface level is 5V or 3.3V
Power supply is 4.5V ~ 5.5V, 3.3V voltage regulator circuit board
Communication interface is a standard SPI interface
4 M2 screw positioning holes for easy installation
Size:4.1 x 2.4cm
Control Interface
A total of six pins (GND, VCC, MISO, MOS1, SCK, CS), GND to ground, VCC is the power supply, MISO, MOS1, 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, MicroSD card toward the direction of the control interface MISO signal is also converted to 3.3V, general AVR microcontroller system can read the signal
