Micro SD Storage Expansion Board Micro SD TF Card Memory Shield Module SPI For Arduino/Winniduino
Support Micro SD and Micro SDHC cards are two micro SD cards (high-speed cards). The communication interface is a conventional SPI interface, and the level conversion circuit board can interface levels of 5V or 3.3V. Interface for Control: GND to ground, VCC is the power supply, MISO, MOSI, SCK is the SPI bus, and CS is the chip select signal pin; 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, and CS is the chip select signal pin; LDO regulator output 3.3V as level converter chip, Micro SD card supply; 3.3V regulator circuit
Micro SD card in the direction of 3.3V signals, Micro SD card in the direction of the control interface The MISO signal is also transformed to 3.3V, allowing it to be read by any AVR microcontroller system.
Since the bomb deck, there has been a Micro SD card connector for convenient card installation and operation. Positioning holes: 4 M2 screws with a 2.2mm diameter positioning hole, convenient to install and achieve inter-module connection;
- 4.5V – 5.5V power supply, 3.3V voltage regulator circuit board
- Positioning holes: 4 M2 screws with a 2.2mm diameter positioning hole
- The control interfaces are GND, VCC, MISO, MOSI, SCK, and CS.
