Microduino-SD aims to read and write data of a memory card. 












==Features==
*Adopt high reliable contact structure as well as a 2.2mm or 2.4mm-thick microsd card holder;
*Small, cheap, stackable and open;
*Open hardware circuit design and Arduino compatible programming development environment;
*Uniformed Microduino interface standard and rich peripheral modules, capable of having a fast and flexible connection and extension with other modules and sensors  in accord with Microduino interface standard;
*Easy to be integrated to pegboards with a 2.45-pitch female header connector interface.

==Specifications==
*The memory card it supports：MicroSD（TF）；

==Document==
Eagle PCB '''[[File:Microduino-SD.zip]]'''

===Main components===
* Card holder：microsd '''[[File:MicroSD.pdf]]'''
* Level conversion chip：TC74HC4050 '''[[File:TC74HC4050AF.pdf]]'''

==Development==
===Arduino library and supported package===
*Adopt adfaruit SD library：
**Original library:（Core+ can't be used directly）【'''[https://github.com/adafruit/SD github download]'''】
**Changed libray：（The spi pin of Core+ has been changed)【'''[[File:Lib SD.zip]]'''】
**SimpleSDAudio:https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Libraries/_06_Microduino_SD_SimpleSDAudio
*Microduino core module can be combined with the sensor module to store and read data,and then analyze, process these data.

==Application==

===Program Download===
Program test：'''[[File:Program Test SD.zip]]'''

===Microduino-SD file read,write,delete test===
*Prepared hardware：Microduino FT232R、Microduino Core、Microduino SD；
*Prepared software：Microduino provides test program（Arduino part）、Arduino IDE（1.0 release and upper）、SD library;
*Put the downloaded library to the libraries folder of Arduino IDE installation;
*Start Arduino IDE，open the test program,board type chosse "Microduino Core (Atmega328P@16M,5V)",download directly；
*Totally four parts，using the OLED to check（If no OLED, you can suse serial monitor):
**CS pin match
**Wirte data to SD card；
**Read specified file's data from SD card；
**Delete file from SD card。
