Czytnik kart micro SD 

The set includes the module and the goldpin strap for self-soldering, the microSD cardcan be purchased separately.


The product is compatible with Arduino

To use the module, you can usethe standard SD library.



The SD cards communicate using the SPI bus. Most of the microcontrollers, including those used inArduinoAVRy, have hardware control of this interface. The functions of the findings are presented in the array below.

Pin Description
GND The ground of the module.
VDD The supply voltage of 5 V.
EN Pin to activate the voltage regulator of 3.3 V. It is pulled up to VDD through a resistor of 100 so the regulator is enabled by default.
CD Card detection. In case of the absence of a pin card, it is in the low status, when the card is in the connector, the status is high. The pin is pulled up to VDD through a resistor of 100.


Selecting device (chip select) in SPI mode. For operation of the module, you must indicate the low status.

Clock line of the SPI bus.


The output data (MISO) in SPI bus.


Input data (MOSI) of the SPI bus.


The output ofthe voltage regulator of 3.3 V.
The module has a built-in regulator and voltage converter so you can connect it directly to boards operating with a voltage of 5 V, for example,Arduino UnoandLeonardo.
