Information

Specification:

This Micro SD Adapter is a Micro SD Reader with an SPI interface. The module can both read and write. Arduino users can get started right away with the Arduino IDE, because the library is already present in the Arduino software.

Module options :

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

2 Contains a level conversion circuit that can interface at 5V or 3.3V

3 Supply voltage is 4.5V ~ 5.5V, Onboard 3.3V voltage regulator

4. SPI Communication Interface

 


The Control Interface consists of 6 Pins (GND, VCC, MISO, MOSI, SCK, CS), GND to ground, VCC is + , MISO, MOSI, SCK  are the SPI buses, CS is the chip select.

3.3V regulator circuit: LDO regulator with a 3.3V output as level converter chip, also Micro SD card power supply;

Level conversion circuit:

Micro SD card in the direction of 3.3 , MicroSD card to the direction of the control interface MISO, signals is also converted to 3.3V, standard AVR microcontrollers can read this signal;
