OpenLog is an open source data logger that works with a simple serial connection and supports micro SD cards up to 64 gb. OpenLog can store or “save” large amounts of serial data and act as a black box to store all serial data produced by the project for science or debugging.
OpenLog runs on a 16MHz internal ATmega328 in an internal crystal. When recording a buffer of 512 bytes, OpenLog draws 6 mA, but since the process takes a fraction of a second, the average current draw will be close to 5 ma. If you record a steady flow at 115200bps, you will be close to the 6mA limit. All data recorded by OpenLog is stored for a micro SD card with a capacity of 64MB to 64GB and a FAT16 or FAT32 file type.
