2pcs Micro SD TF Memory Card Reader Module with SPI interface For Arduino For Sale

2 Pieces Micro SD Memory Card Storage Board Module with SPI Interface For Arduino
This MicroSD Card Adapter module is a Micro SD card reader module with an SPI interface via the file system driver, requiring an Arduino (or comparable) microcontroller system to complete the MicroSD system to read and write files.
Arduino users can directly use the Arduino IDE that comes with an SD card to complete the library card initialization and Micro SD and Micro SDHC cards (high speed card)

The level conversion circuit board can interface with 5V or 3.3V levels

The power supply input (Vcc) is 4.5V to 5.5V. The module includes an AMS1117-3.3 3.3V voltage regulator circuit to support the 3.3V level requirements

The communication interface is a standard SPI interface

4x M2 screw positioning holes (2.2mm diameter) for easy installation

Interface Description:

• Control Interface: Six pin header (GND, VCC, MISO, MOSI, SCK, CS)
• GND: Ground
• VCC: DC power supply input - 4.5V to 5.5V
• MISO, MOSI, SCK: SPI bus,
• CS: Chip select signal pin

3.3V regulator circuit:

• AMS1117-3.3 LDO regulator output 3.3V for level conversion chip, Micro SD card supply

Level conversion circuit:

• Micro SD card to signal the direction of converts 3.3V, MicroSD card interface to control the direction of the MISO signal is also converted to 3.3V, general AVR microcontroller systems can read the signal
