Support Micro SD card, Micro SD HC card (high speed card) Onboard level conversion circuit, that is, the interface level can be 5V or 3.3V The power supply is 4.5V~5.5V, and the onboard 3.3V voltage regulator circuit Current: 0.2-200mA Communication interface: SPI 4PCS M2 screw positioning holes, easy installation Pin of micro S D card TF card read write module; Control interface: a total of 6 pins (GND, VCC, MISO, MOSI, SCK, CS), GND is the ground, VCC is the power supply, MISO, MOSI, SCK are the SPI bus, and CS is the chip selection signal pin; 3.3V voltage stabilizing circuit: The 3.3V output of the LDO voltage stabilization is the power supply for the level conversion chip and the Micro SD card; Level conversion circuit: the signal to the Micro SD card is converted to 3.3V, and the MISO signal from the Micro SD card to the control interface is also converted to 3.3V, which can be read by the general AVR microcontroller system; Please make sure the card format is FAT32 Package include: 10 x Micro SD card module

Micro SD card connector: since the bomb deck for easy card insertion and removal, mounting holes: 4 M2 screws positioning hole diameter of 2.2mm, easy to install positioning, to achieve inter-module combination. 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 storage expansion board 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. The level conversion circuit board that can interface level is 5V or 3.3V, communication interface is a standard SPI interface. Micro SD storage expansion board support micro SD card, micro SDHC card (high-speed card),voltage: 4.5V~5.5V DC; Communication Interface: Standard SPI; Interface Voltage Level: 3.3V or 5V; Applicable card type: Micro SD card, micro SDHC card.
