The module (MicroSD Card Adapter) is a Micro SD card reader module,drive programming through the file system and the SPI interface
Product Overview & Technical Specifications
The module (MicroSD Card Adapter) is a Micro SD card reader module,drive programming through the file system and the SPI interface.singlechip system can complete the MicroSD card reading and writing files. Arduino users can directly use the Arduino IDE built-in SD card library to complete the card initialization and read and write.
The module features are as follows:
- support Micro SD card, Micro SDHC card (high cards)
- board level conversion circuit, which can be 5V or 3.3V interface level
- power supply for 4.5V~5.5V, the on-board 3.3V regulator circuit
- communication interface is standard SPI interface
- 4 M2 screw positioning holes, easy to install
Interface description:
Control interface: a total of 6 pins (GND, VCC, MISO, MOSI, SCK, CS), GND, VCC power supply, MISO, MOSI, SCK, SPI bus, CS chip select signal pin;
The 3.3V regulator circuit:LDO regulated output 3.3V level conversion chip, Micro SD card power supply;
Level conversion circuit: signal to Micro SD direction into 3.3V, MicroSD card into the MISO signal to control the interface direction is converted to 3.3V, general AVR single-chip microcomputer system can read the signal;
Micro SD card: since the bomb type clamping, convenient card plug.
A positioning hole: 4 M2 screw location hole, aperture is 2.2mm, the module to facilitate the installation location, module combination;
