Introduction

Heads up! This tutorial is for the Qwiic Open Log for I2C [ DEV-15164 ]. If you are using the OpenLog for serial UART [ DEV-13712 ], please refer to the OpenLog Hookup Guide.

The SparkFun Qwiic OpenLog is the smarter and better looking cousin to the extremely popular OpenLog. We’ve ported the original serial based interface to I2C. Now you can daisy chain multiple I2C devices and log them all without taking up your serial port. Pop in a microSD card, write some simple code, and your data will be recorded to a text file on the microSD card.
