Qwiic OpenLog Hookup Guide

Contributors: Nate, Toni_K, Ell C, Englandsaurus

Introduction

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.
