Reading and Writing SD Card Breakout Board - (AD1992)

Description:

Make your SD application easier and simpler. It connects easily as a peripheral to your Arduino sensor shield module. Through programming, you can read and write to the SD card using your Arduino. It can be used for SD cards more easily, such as for MP3 players, MCU system control, ARM.

Specifications:

- Supports SD, SDHC cards

- The level conversion circuit board can interface with 5Vdc or 3Vdc

- The communication interface is standard SPI

- Control interface: a total of 6 pins (GND, VCC, MISO, MOSI, SCK, CS). GND to ground, VCC is the power supply; MOSI, MISO, and SCK are the SPI bus. CS is the Chip Select pin.

- 3.3V regulator circuit. The 3.3Vdc output LDO regulator acts as a level converter chip, powering the Micro SD card.

- Level conversion circuit: MicroSD card in the direction of 3.3Vdc signals.
