The SparkFun OpenLog is an open source data logger that works over a simple serial connection and supports microSD cards up to 32GB. The OpenLog can store or “log” huge amounts of serial data and act as a black box of sorts to store all the serial data that your project generates, for scientific or debugging purposes.
The SparkFun OpenLog uses an ATmega328 running at 16MHz thanks to the onboard resonator. The OpenLog draws approximately 2-3mA in idle (nothing to record) mode. During a full record OpenLog can draw 10 to 20mA depending on the microSD card being used.
All data logged by the OpenLog is stored on the microSD card. Any 512MB to 32GB microSD card should work. OpenLog supports both FAT16 and FAT32 SD formats.

該SparkFun OpenLog是一個開源的數據記錄儀的作品通過簡單的串行連接,並支持microSD存儲卡容量高達64GB。該OpenLog可存儲或“日誌”巨大的串行數據和行為的金額由各種各樣的黑盒子來存儲所有您的項目生成,為科學或調試目的串行數據。
在SparkFun OpenLog逃跑板載ATmega328的,為16MHz由於運行記錄一個512字節的緩衝區,當板載crystal.The OpenLog吸引6毫安,但因為這過程需要幾分之一秒,平均電流消耗接近5mA的。但請記住,如果你是在錄製115200BPS一個恆定的數據流,將接近該6毫安限制。由OpenLog記錄的所有數據都存儲涉及64MB到64GB容量和FAT16或FAT32文件類型的功能在microSD卡上。
