描述

SparkFun OpenLog microSD 數據記錄 ATmega328 開發板 SparkFun 原裝進口

SparkFun OpenLog 是一款開源數據記錄器，可通過簡單的串行連接進行工作，並支持最高64GB的microSD卡。出於科學或調試目的， SparkFun OpenLog 可以存儲或“記錄”大量的串行數據，並作為一個黑盒來存儲項目生成的所有串行數據。 SparkFun OpenLog 運行於板載ATmega328上，運行頻率為16MHz，這要歸功於板載晶振。在記錄512字節緩衝區時，OpenLog消耗6mA電流，但由於該過程需要幾分之一秒的時間，平均電流消耗接近5mA。請記住，如果您以115200bps的速度錄製恆定的數據流，則會達到6mA的限制。OpenLog記錄的所有數據都存儲在microSD卡上，涉及64MB至64GB容量和FAT16或FAT32文件類型的功能。

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 on 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.

FEATURES

• VCC Input: 3.3V-12V (Recommended 3.3V-5V)
• Log to low-cost microSD FAT16/32 cards up to 64GB
• Simple command interface
• Configurable baud rates (up to 115200bps)
• Preprogrammed ATmega328 and bootloader
• Four SPI pogo pins
• Two LEDs indicate writing status
• 2mA idle, 6mA at maximum recording rate
