Description
The module of the reader of micro SD cards with goldpin connectors – 2.54 mm pitch. It communicates with the main board via SPI interface. It works with a supply voltage from 3.3 V to 5 V.
Pin Configuration of Micro SD Card Adapter Module
The module contains 6 pins for power and communicating with the controller. The table below describes the pin type and role of each pin on the module.
| Pin Type | Pin Description |
| GND | Ground |
| VCC | Voltage Input |
| MISO | Master In Slave Out(SPI) |
| MOSI | Master Out Slave In(SPI) |
| SCK | Serial Clock(SPI) |
| CS | Chip Select(SPI) |
Sensor maintenance
The SD card communicates using the SPI bus. Most of the microcontrollers, including those used in Arduino, AVR,have hardware to verify this interface.
| The product is compatible with STM32 The module works with the built-in examples in the Arduino IDE. |
