Product Description
Expand the memory of your microcontroller projects with the Mini Micro SD Card Reader Module. This module allows you to read from and write to standard Micro SD cards, making it ideal for data logging, storing configuration files, or playing audio files. At Robogears, we recommend this specific module because it features an on-board level conversion circuit. This means you can safely connect it to a 5V Arduino Uno or a 3.3V ESP32 without worrying about damaging your SD card's sensitive logic. Whether you are building a weather station that logs data every minute or a DIY MP3 player at your Pimpri workshop, this SPI-based reader provides a reliable and high-speed storage solution.
Detailed Key Features
Integrated Level Shifter: Built-in 74VHC125 or equivalent buffer converts 5V signals to 3.3V, ensuring high-speed data integrity and card safety.
Standard SPI Communication: Uses only 4 signal pins (MISO, MOSI, SCK, CS), leaving plenty of GPIOs free for other sensors and actuators.
On-board 3.3V Regulator: Includes a dedicated LDO to provide clean power to the SD card, even when powered from a 5V rail.
High Compatibility: Supports both standard Micro SD and Micro SDHC cards (formatted to FAT16 or FAT32).
M3 Mounting Holes: Features four positioning holes for secure attachment to your robot's chassis or project enclosure.
