A Serial Micro-SD Card Module is a small, easy-to-use device that allows the user to add removable storage to projects and development boards. It enables users to store and manipulate data more easily. The module supports standard SD, SDHC, and Micro-SD cards, and utilizes a serial interface for data transfer. It is compatible with a variety of development boards and microcontrollers, including Arduino, Raspberry Pi, and ESP32. The module can be used for data logging, file storage, and other applications. Support Micro SD Card with your Ardunio and non-Ardunio projects with this Micro SDHC card (high-speed card)The level conversion circuit board that can interface level is 5V or 3.3VCommunication interface is a standard SPI interfaceWith mounting holes of 4 x M2 screws positioning holes of diameter of 2.2mm to allow for easy to installation and positioning and allow for inter-module combinations. 1. Support Micro SD Card, Micro SDHC card (high-speed card) 2. The level conversion circuit board that can interface level is 5V or 3.3V 3. Communication interface is a standard SPI interface 4. Control Interface: A total of six pins (GND, VCC, MISO, MOSI, SCK, CS), GND to ground, 5. VCC is the power supply, MISO, MOSI, SCK is the SPI bus, CS is the chip select signal pin; 6. 3.3V regulator circuit: LDO regulator output 3.3V as level converter chip, Micro SD card supply; 7. Level conversion circuit: Micro SD card into the direction of signals into 3.3V, MicroSD card toward the direction of the control interface MISO signal is also converted to 3.3V, general AVR microcontroller system can read the signal; 8. Micro SD card connector: yes since the bomb deck for easy card insertion and removal. 9. mounting holes: 4 M2 screws positioning hole diameter of 2.2mm, easy to install positioning, to achieve inter-module combination.
