Micro SD Card SPI Interface Module Reader Writer with Level Conversion Chip

Supports Micro SD card, Micro SDHC card (high speed card)
Onboard level shifting circuit, ie the interface level can be 5V or 3.3V
Power supply is 4.5V~5.5V, onboard 3.3V regulator circuit
Communication interface is standard SPI interface
M2 screw positioning holes for easy installation

Control interface : a total of 6 pins (GND, VCC, MISO, MOSI, SCK, CS), GND is ground, VCC is the power supply, MISO, MOSI, SCK is the SPI bus, CS is the chip select signal pin; 3.3V voltage regulator circuit : 3.3V of LDO regulated output is power supply for level conversion chip and Micro SD card.

Level conversion circuit : The signal to the direction of the Micro SD card is converted to 3.3V, and the MISO signal of the MicroSD card to the control interface is also converted to 3.3V. Generally, the AVR microcontroller system can read the signal.

Through programming, you can read and write to the SD card using your Arduino

Makes your SD application easier and simple.
