Features:

• Micro memory card support (high-speed card)
• Level conversion board that can connect to 5V or 3.3V
• Communication interface: Standard SPI interface
• Control interface: Set of six pins (GND, VCC, MISO, MOSI, SCK, CS), GND for grounding, VCC for power supply, MISO, MOSI, SCK is the SPI line, CS is the chip select signal pin
• 3.3V switch regulator: LDO regulator that produces 3.3V as a level conversion chip, Micro memory card supply
• Level conversion board: The Micro memory card converts signals to 3.3V, and the MISO control interface signal is also converted to 3.3V, allowing general AVR microcontroller systems to read the signal
• Micro memory card connector: Available, designed for easy insertion and removal of the card
• Mounting holes: 4 M2 mounting holes with a diameter of 2.2mm, easy installation and achieving combination between modules
