The SparkFun Arduino UNO R4 WiFi Qwiic Kit is a great way to get started with Arduino and the Qwiic-connect system - use this guide to get started!

Monitor your LiPo battery with the LiPo fuel gauge! In this tutorial, we will be using the MAX17043 and MAX17048 to monitor a single cell, LiPo battery over the Arduino Serial Monitor. We will also connect a display to view the output without the need to connect the microcontroller to a computer.

The SparkFun Audio Codec Breakout - WM8960 is a low power, high quality stereo codec chock full of features. In this tutorial, some of these features by using an Arduino microcontroller to configure the audio codec and pass audio to the headphone or speaker channels.

The SparkFun Qwiic Speaker Amp includes the Texas Instruments TPA2016D2 stereo, filter-free class-D audio power amplifier. This tutorial will help you get started and configure the amplifer settings using an Arduino microcontroller.

Using WiFi to send sensor data from an ESP32 to a WiFi network and be able to read it from an IoT Dashboard from anywhere in the world.

Get started with the SparkFun Level Shifter - 8 Channel (TXS0108E) Breakout to shift between 5V, 3.3V and 1.8V logic level systems.

Get started with SparkFun's newest Buck Regulator Boards - the BabyBuck and the Buck!

Running out of memory? Don't forget to check out the Qwiic EEPROM!

The SparkFun Qwiic MultiPort adds additional ports to boards that have only one Qwiic port on their I2C bus. Once added, you can use it as a hub to add as many I2C devices to the bus as you need! You can also use the board as an alternative to a daisy chained configuration.

The SparkFun ProDriver and Mini Stepper Motor Driver boards utilize Toshiba's TC78H670FTG stepper motor driver. The ProDriver features latch pin terminals, which are easier to connect than the "Easy" Drivers. Meanwhile, the Mini Stepper Motor Driver come in smaller PCB footprint, that is pin compatible with breadboards. To get started, follow this hookup guide and you will be spinning stepper motors, in no time.

The SparkFun Clock Generator 5P49V60 (Qwiic) breakout board offers a wide range of customizable frequencies in a wide range of different signal types using a single reference clock. This hookup guide will go over all of the many available functions and gives the hardware rundown on what exactly is on this board.

Protect your project by adding a fuse in your circuit to save it from molten destruction.

A quick primer to get you going with the PCA9306 Logic Level Converter - a dedicated I2C translator.

Need to add more analog inputs for your project? Check out the Qwiic 12-bit ADC.

The essential parts for beginning (or even experienced) hobbyists that gives you all of the basic through-hole components you will need to get started playing with embedded projects. We'll identify a few parts in the kit and provide a few basic circuits to get started!

The Single Supply Logic Converter allows you to bi-directionally translate signals from a 5V or 3.3V microcontroller without the need for a second power supply! The board provides an output for both 5V and 3.3V to power your sensors. It is equipped with a PTH resistor footprint for the option to adjust the voltage regulator on the low side of the TXB0104 for 2.5V or 1.8V devices.

Have a bunch of sensors with the same I2C address? Put them on the Qwiic MUX (TCA9548A) to get them all talking on the same bus!

Learn how to extend the range of your I2C communication bus with the Qwiic differential I2C bus extender (PCA9615 ) breakout board.
