5pcs Micro SD Storage Board TF Card Reader Memory Shield Module SPI for Arduino |5pcs Micro SD(TF) Storage Board, Micro SD Card Slot, Supports SDIO and SPI Interfaces, 2.54mm Pitch Pinheaders.

x5pcs Micro SD Storage Board TF Card Reader Memory Shield Module SPI DESCRIPTION: SPI interface via file system driver, microcontroller system to complete the MicroSD card reading and writing functions. Arduino users can use Arduino IDE comes with an SD card to complete the library card initialization and read-write directly. Power supply:4.5V ~ 5.5V, 3.3V voltage regulator circuit board. Communication interface: a standard SPI interface. Interface effect: 1. Control Interface: Six pins (GND, VCC, MISO, MOSI, SCK, CS), GND to ground, VCC is power supply, MISO, MOSI, SCK is SPI bus, CS is chip selecting signal pin 2. 3.3V voltage regulator circuit: LDO regulator output 3.3V 3. Level conversion circuit: signal of Micro SD card direction into 3.3V, MISO signal which controls interface direction is also converted to 3.3V. general AVR microcontroller system can read the signal; 4. Micro SD card connector: self-spring socket, easy to insertion and removal card 5. Positioning holes: 4pcs 2mm diameter M2 screws hole, good for installing positioning, to achieve inter-module combination FEATURES: Supply voltage: 4.5V(min), 5V(typical), 5.5V(max) Current: 0.2mA(min), 80mA(typical), 200mA(max) Level conversion circuit board can interface: 5V or 3.3V Card supported: Micro SD card (<=2G),Mirco SDHC card (<=32G) Size: approx. 42 x 24 x 12mm Weight: approx. 5g Interface effect PACKET CONTAINS: 5pcs x Micro SD Shield Module for Arduino
