The board allows you to attach cables to the microSD / TF card line. Supply voltage from 2.7 to 3.6 V. Polol 2597
The board outputs the lines of the microSD card , so it can be connected via SPI l. The module supply voltage and the logic level of the digital lines range from 2.7 to 3.6 V, in order to use the module with 5 V systems it is necessary to use a logic level converter , you can also use a ready module with a built-in stabilizer and converter . The 2.54mm pitch leads allow the module to be placed in the contact plate.
