Micro SD 記憶卡讀寫模組 Micro SDHC 卡讀寫卡器 SPI介面 帶3.3/5V電位轉換
Micro SD 記憶卡讀寫模組 （MicroSD Card Adapter）是 (Micro SD / Micro SDHC )卡讀寫模塊，通過文件系統及SPI接口驅動程序，單片機系統即可完成MicroSD卡內的文件進行讀寫。Arduino用戶可直接使用Arduino IDE自帶的SD卡程序庫即可完成卡的初始化和讀寫
Micro SD 記憶卡讀寫模組 特點如下：
- 1.支持Micro SD卡、Micro SDHC卡（高速卡）
- 2.板載電平轉換電路，即接口電平可為5V或3.3V
- 3.供電電源為4.5V~5.5V，板載3.3V穩壓電路
- 4.通信接口為標準SPI接口
- 5.4個M2螺絲定位孔，便於安裝
控制接口：共6個引腳（GND、VCC、MISO、MOSI、SCK、CS），GND為地，VCC為供電電源，MISO、MOSI、SCK為SPI總線，CS為片選信號腳；
3.3V 穩壓電路：LDO穩壓輸出的3.3V為電平轉換芯片、Micro SD卡供電；
電平轉換電路：往Micro SD卡方向的信號轉換成3.3V，MicroSD卡往控制接口方向的MISO信號也轉換成了3.3V，一般AVR單片機系統都能讀取該信號；
Micro SD 卡座：是自彈式卡座，方便卡的插拔。
定位孔：4個M2螺絲定位孔，孔徑為2.2mm，使模塊便於安裝定位，實現模塊間組合；
