Product Details
Micro SD Card Reader Module with SPI Interface and 3.3V Regulator (SKU: 11566)
The Micro SD Card Reader Module is an essential component for any embedded project requiring persistent, high-capacity data storage. It provides a simple and reliable way to interface Micro SD cards with microcontrollers like Arduino, ESP32, or Raspberry Pi Pico.
This module operates using the fast Serial Peripheral Interface (SPI) protocol, requiring connection to the MISO (Master In Slave Out), MOSI (Master Out Slave In), SCK (Serial Clock), and CS (Chip Select) pins on the host microcontroller. A key feature is the on-board 3.3V voltage regulator, which ensures the Micro SD card receives the correct operating voltage, while the module itself can be conveniently powered directly from a standard 5V DC supply (range 4.5V to 5.5V). The pinout also includes GND and VCC. Its small size and pre-drilled M2 mounting holes make integration into custom enclosures and PCBs straightforward.
