Micro SD Storage Board Mini TF Card Memory Reader Shield Module SPI For Arduino

Supports Micro SD card, Micro SDHC card (high speed card) Board level conversion circuit, interface for 5V or 3.3V Power supply 4.5V ~ 5.5V, 3.3V voltage regulator circuit board Communication interface, standard SPI. 5.4 M2 screw positioning holes for easy installation Interface Description: Control Interface: A total of six pins (GND, VCC, MISO, MOSI, SCK, CS), GND to ground, VCC is the power supply, MISO, MOSI, SCK for SPI bus, CS is the chip select signal pin; 3.3V regulator circuit: LDO regulator output 3.3V for level conversion chip, Micro SD card supply; Level conversion circuit: Micro SD card to signal the direction of converts 3.3V, MicroSD card interface to control the direction of the MISO signal is also converted to 3.3V, general AVR microcontroller systems can read the signal; Micro SD card connector: self bomb deck, easy card insertion. Positioning holes: 4 M2 screws positioning holes with a diameter of 2.2mm, so the module is easy to install positioning, to achieve inter-module combination
