Micro SD Card SPI Module for Arduino

Description

Micro SD Card SPI Module for Arduino The Micro SD Card SPI Module for Arduino provides a simple way to read and write files on a Micro SD or TF memory card. It communicates with the microcontroller through the standard SPI interface. This module works well for projects that need removable storage. For example, you can save sensor readings, system events, configuration files, text, or audio data. In addition, the onboard voltage regulator supplies the low voltage required by the memory card. Therefore, the module offers convenient integration with many development boards. Key Features Supports Micro SD and TF memory cards Uses the standard SPI communication interface Onboard 3.3V voltage regulator Easy connection to Arduino development boards Works with compatible ESP8266, ESP32, STM32, and Raspberry Pi systems Suitable for reading and writing different file types Removable and reusable storage solution Compact design for embedded projects Standard pin headers for easy wiring Compatible with common SD card software libraries Technical Specifications Product Type: Micro SD card reader module Supported Media: Micro SD / TF cards Communication: SPI Onboard Regulation: 3.3V Typical Supply Input: 5V DC Logic Interface: SPI-compatible Card Socket: Push-in Micro SD card slot Installation: PCB module with pin headers Module Pinout VCC: Module power input GND: Ground connection CS: SPI chip-select signal SCK: SPI clock signal MOSI: Data from the controller to the card MISO: Data from the card to the controller Always check the labels printed on your module before connecting the pins. Some production versions may arrange the pins differently. Applications This module suits many storage and data-recording projects, including: Temperature and humidity data loggers Weather monitoring stations GPS tracking and route recording Arduino file-storage projects Audio playback systems CNC and 3D printer controllers Robotics and automation projects Configuration and calibration storage Portable measurement equipment Embedded monitoring systems Important Usage Notes Micro SD cards use low-voltage signaling. However, the exact regulator and logic-level circuit can vary between module versions. Check the board markings before connecting it to a 3.3V controller. Furthermore, card capacity and file-system support depend on the selected memory card, controller, and software library. Format the card with a compatible file system before use. Finally, disconnect the power before inserting, removing, or rewiring the module during development. Package Includes 1 × Micro SD Card Reader Module Note: The package does not include a Micro SD memory card.
