The Qwiic OpenLog can store, or \"log\", huge amounts of serial data and act as a black box of sorts to store all the data that your project generates, for scientific or debugging purposes. Utilizing the handy Qwiic system, no soldering is required to connect it to the rest of your system. However, SparkFun still have broken out 0.1\"-spaced pins in case you prefer to use a breadboard.\u003c\/p\u003e\n\u003cp\u003eLike its predecessor, the SparkFun Qwiic OpenLog runs off of an onboard ATmega328, running at 16MHz thanks to the onboard resonator. The ATmega328 has been sure to feature the Optiboot bootloader loaded, which allows the OpenLog to be compatible with the “Arduino Uno” board setting in the Arduino IDE. It is important to be aware that the Qwiic OpenLog draws approximately 2mA-6mA in idle (nothing to record) mode, however, during a full record the OpenLog can draw 20mA to 23mA depending on the microSD card being used.\u003c\/p\u003e\n\u003cp\u003eThe Qwiic OpenLog also supports clock stretching, which means it performs even better than the original and will record data up to 20,000 bytes per second at 400kHz. As the receive buffer fills up this OpenLog will hold the clock line, letting the master know that it is busy. Once the Qwiic OpenLog is finished with a task, it releases the clock thus allowing the data to continue flowing without corruption. For even better performance the \u003ca href=\"\/en-eu\/products\/sparkfun-openlog-artemis\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eOpenLog Artemis\u003c\/a\u003e is the tool you need, featuring logging speeds up to 500000bps.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e The SparkFun Qwiic OpenLog supports 64MB to 32GB microSD cards in both FAT16 and FAT32 formats.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e The I2C address of the OpenLog is 0x2A and is jumper selectable to 0x29.
