The PicoBuck board is a high-efficiency three-channel constant-current LED driver.

An overview of the Bi-Directional Logic Level Converter, and some example circuits to show how it works.

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

EEPROM is a great way to add extra memory to your microcontroller project. Wait 'til you see how easy it is to use!

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.

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

An introduction to integrated circuits (ICs). Electronics' ubiquitous black chips. Includes a focus on the variety of IC packages.

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

A tutorial on electronics' most overlooked and underappreciated component: the switch! Here we explain the difference between momentary and maintained switches and what all those acronyms (NO, NC, SPDT, SPST, ...) stand for.

How to use the level translating µSD device.

How to assemble and use the Cherry MX Switch Breakout, allowing you to turn a matrix of mechanical switches into a full-size keyboard!

This is a quick hookup to help you get started with the MCP4725 DAC breakout board. This device allows you to send analog signal from a digital source, like the I2C interface on the Arduino microcontroller.

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.

An overview of the flex sensor - a bendable variable resistor. Plus, example circuits and Arduino code to get you started!

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

How to use the TXB0104 chip.

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.
