Features

• Description
• The SparkFun OpenLog with Headers 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. This version of th OpenLog even includes pre-soldered headers for your convenience.
• 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.
• For even better performance the OpenLog Artemis is the tool you need, featuring logging speeds up to 500000bps.
