Product description: microSD card reader module - Joy-IT COM-MSD
The Joy-IT COM-MSD is a small module designed to support microSD cards via the SPI bus. This solution allows you to easily expand the capabilities of the microcontroller with the ability to read and write data from storage media . The module operates with a supply voltage and logic levels of 3.3V , so a logic level converter is required when working with 5V boards. Thanks to its compact design , the module can be easily installed in mobile devices, data loggers, IoT projects, and automation systems. The manufacturer provides sample implementations for the Arduino IDE and Raspberry Pi Pico using MicroPython , significantly speeding up the start of work with the module.

- SPI interface : provides communication with popular microcontrollers and embedded platforms
- Operating voltage 3.3 V : the module is adapted to systems operating with 3.3 V logic
- Compact design : small dimensions make it easy to integrate into existing projects
- Support for Arduino and Raspberry Pi : the manufacturer provides sample connections and code
- Easy integration : the module will work well in data recording systems and IoT projects
SPI module pinouts and compatibility
The module is equipped with standard SPI interface pins: CS, MOSI, MISO, and CLK , as well as 3.3V and GND power pins . This allows it to work with a wide range of microcontrollers and single-board computers supporting SPI communication. The chip is compatible with platforms such as Arduino , Raspberry Pi , ESP32 , STM32 , and other systems operating with 3.3V logic. For boards using 5V logic, a logic level converter is recommended. For Arduino operation, you can use the SD library available in the Arduino IDE , while MicroPython and the sdcard.py library are ideal for Raspberry Pi projects. This solution allows for quick file reading and writing in educational projects, prototypes, and embedded devices.
