The module (microSD card adapter) is a micro SD card reader module and the spi interface via the file system driver, micro controller system to complete the micro SD card read and write files. Users can directly use the Arduino ide comes with an SD card to complete the library card initialization and read write features: support micro SD card, micro sdhc card (high-speed card) the level conversion circuit board that can interface level is 5v or 3.3V power supply is 4.5V – 5.5V, 3.3V voltage regulator circuit board communication interface is a standard spi interface 4 m2 screw positioning holes for easy installation control interface: a total of six pins (gnd, vcc, miso, mosi, sck, cs), gnd to ground, vcc is the power supply, miso, mosi, sck is the spi bus, cs is the chip select signal pin; 3.3V regulator circuit: ldo regulator output 3.3V as level converter chip, micro SD card supply 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 micro SD card connector: yes since the bomb deck for easy card insertion and removal positioning holes: 4 m2 screws positioning hole diameter of 2.2mm, the module is easy to install positioning, to Achieve intermodule combination micro SD card interface module: control interface: a total of six pins (gnd, vcc, miso, mosi, sck, cs), gnd to ground, vcc is the power supply, miso, mosi, sck is spi bus, cs is the chip select signal pin 3.3V voltage regulator circuit: ldo regulator output is 3.3V level converter chip, micro SD card supply level conversion circuit: micro SD card into the direction of the signal is converted to 3.3V, microSD card interfaces to control the direction of the miso signal is also converted into 3.3V, general avr microcontroller system can read the signal; micro SD card connector: a self bomb deck, easy card insertion. Positioning holes: 4 m2 screws positioning hole diameter is 2.2mm, the positioning of the module is easy to install, to Achieve inter module combination.
Input Supply Voltage (VDC):4.5V to 5.5V (This is the required voltage range to power the module.)
The module includes an onboard 3.3V voltage regulator, which helps ensure that the SD card operates at the correct voltage level (3.3V), even if the supply voltage is higher (e.g., 5V from an Arduino).
The dimensions of the module are 40 mm x 24 mm, making it compact and easy to integrate into small projects.
The mounting holes are designed to fit M2 screws, which allows easy attachment to project enclosures or PCB assemblies.
The module weighs approximately 4 grams, making it lightweight and easy to add to your projects without adding much weight.
The shipping weight of the module is approximately 0.005 kg, meaning it is very light and ideal for shipping with other small components.
The package size is around 9 cm x 5 cm x 2 cm, which is compact for easy packaging and handling.
