SparkFun OpenLog Data Logger
Open source data logger
Supports microSD cards of up to 32 GB
Four SPI pogo pins
RoHS compliant
The SparkFun OpenLog Data Logger is an open source data logger that works over a simple serial connection and supports microSD cards up to 32 GB. 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 16 MHz thanks to the onboard resonator. The OpenLog draws approximately 2-3 mA in idle (nothing to record) mode. During a full record OpenLog can draw 10 to 20 mA depending on the microSD card being used.
All data logged by the OpenLog is stored on the microSD card. Any 512 MB to 32 GB 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 500000 bps.
