## Description

The SparkFun OpenLog is an open-source serial data logger based on the ATmega328 running at 16 MHz. It logs incoming serial data directly to a microSD card, supporting cards from 64 MB to 64 GB in FAT16 or FAT32 format. Simply connect a serial line from your project to the OpenLog, and all transmitted data is stored to the card as text files. The OpenLog draws approximately 5 mA on average, rising to around 6 mA when actively writing a 512-byte buffer. It supports configurable baud rates and is well suited for long-term data acquisition, debugging, and any application where a record of serial output is needed.
