Product description

This module (MicroSD Card Adapter) is a micro SD card read-write module. Through the file system and SPI interface driver, the microcontroller system can read and write files in the MicroSD card. The SD card library provided with IDE can complete the initialization, reading and writing of the card

1. Support Micro SD card, Micro SDHC card (high-speed card)

2. On board level conversion circuit, i.e. the interface level can be 5V or 3.3V

3. The power supply is 4.5V~5.5V, and the on-board 3.3V voltage stabilizing circuit

4. The communication interface is a standard SPI interface

5.4 M2 screw positioning holes for easy installation

Control interface: a total of 6 pins (GND, VCC, MISO, MOSI, SCK, CS). GND is the ground, VCC is the power supply, MISO, MOSI, SCK is the SPI bus, and CS is the chip signal pin;

3.3V voltage stabilizing circuit: 3.3V of LDO voltage stabilizing output supplies power for level conversion chip and Micro SD card;

Level conversion circuit: the signal in the direction of Micro SD card is converted to 3.3V, and the MISO signal in the direction of control interface of MicroSD card is also converted to 3.3V, which can be read by general AVR microcontroller system;

Micro SD card holder: It is a self elastic card holder, convenient for card insertion and removal.

Positioning holes: 4 M2 screw positioning holes, with a hole diameter of 2.2mm, to facilitate the installation and positioning of modules and realize the combination between modules
