SparkFun OpenLog 資料紀錄器 最高支援到 64G 記憶卡

SparkFun OpenLog 是一個開源數據記錄器，可以通過簡單的串行連接工作，並支持高達64GB的 microSD 卡。OpenLog可以存儲或“記錄”大量的串行數據，並且作為一個黑匣子，用於存儲項目生成的所有串行數據，用於科學或調試。

由於板載晶振，SparkFun OpenLog內置了 ATmega328，運行速度為16MHz。當記錄512字節緩衝區時，OpenLog會吸收6mA的電流，但是由於該過程需要幾分之一秒的時間，平均電流消耗將接近5mA。請記住，如果您以115200bps的速度錄製恆定的數據流，您將接近6mA的限制。由OpenLog記錄的所有數據都存儲在microSD卡上，這些存儲介質具有64MB到64GB的容量以及FAT16或FAT32文件類型的功能。

特徵

• VCC輸入：3.3V-12V（推薦3.3V-5V）
• 儲存方案 低成本的 microSD FAT16 / 32記憶卡, 最高支援到 64GB
• 簡單的命令界面
• 波特率可配置（高達115200bps）
• 預編程的ATmega328和引導加載程序
• 四個SPI pogo引腳
• 兩個LED指示寫入狀態
• 2mA空閒，最大錄像速度為6mA

SparkFun OpenLog

The SparkFun OpenLog is an open source data logger that works over a simple serial connection and supports microSD cards up to 64GB. 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 runs off of an onboard ATmega328, running at 16MHz thanks to the onboard crystal.The OpenLog draws 6mA when recording a 512 byte buffer, but as that process takes a fraction of a second, the average current draw is closer to 5mA. Keep in mind though that if you are recording a constant data stream at 115200bps, you will approach that 6mA limit. All data logged by the OpenLog is stored on the microSD card that involve the features of 64MB to 64GB capacity and FAT16 or FAT32 file type.

Note: The latest version of the firmware (included with this board) does not compile in Arduino 1.6.7. You will need to compile in 1.6.5.
