Using the super blazing, nay blinding, fast SAMD21 whipping clock cycles at 48MHz and the RFM96 module to connect to the Things Network (and other Radio woodles).

MicroPython is an implementation and subset of the Python 3 programming language that can be used on microcontrollers. This guide will walk you through writing MicroPython programs for the ESP32 Thing development board.

Learn the options for powering your LilyPad projects, LiPo battery safety and care, and how to calculate and consider power constraints on your projects.

The Melexis MLX90640 contains a 32x24 array of thermopile sensors creating, in essence, a low resolution thermal imaging camera. In this guide, we’ll go over how to connect your Qwiic Infrared Array with MLX90640 and get it communicating with Processing to produce a nice thermal image.

In this tutorial, we look at various methods for running a script or program automatically whenever your Raspberry Pi (or other Linux computer) boots up.

Learn about the latest generation of GPS and GNSS receivers to get 14mm positional accuracy!

Learn the tips and tricks to use the u-blox software tool to configure your GPS receiver.

Find out where you are! Use this easy hook-up guide to get up and running with the SparkFun high precision GPS-RTK NEO-M8P-2 breakout board.

Hookup guide for the MAX98357A I2S audio breakout board.

This tutorial will show you how to load the MicroPython interpreter onto a variety of development boards.

In this digital fabrication project featuring 3D printing, laser cutting, and DIY electronics, you will build a beautiful design object for your desktop or night stand.

Using the ESP32 LoRa 1-CH Gateway as a gateway and device, and pushing data to The Things Network.

Tkinter is the standard graphical user interface package that comes with Python. This tutorial will show you how to create basic windowed applications as well as complete full-screen dashboard examples complete with live graph updates from matplotlib.

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.

The AVR-based Qwiic Serial Enabled LCDs are a simple and cost effective solution to include in your project. These screens are based on the HD44780 controller, and include ATmega328P with an Arduino compatible bootloader. They accept control commands via Serial, SPI and I2C (via PTH headers or Qwiic connector). In this tutorial, we will show examples of a simple setup and go through each communication option.

In this tutorial, we will use a Raspberry Pi 3 and the Pi AVR Programmer HAT to program an ATMega328P target. We are going to first program the Arduino bootloader over SPI, and then upload an Arduino sketch over a USB serial COM port.

Use matplotlib to create a real-time plot of temperature data collected from a TMP102 sensor connected to a Raspberry Pi.

Learn about the button and switch offerings in the LilyPad line and how to use them.

Is your finger bent? Is your finger straight? The Qwiic Flex Glove controller board will answer this age old question for you with the flex sensor!

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!

This guide will help you get started with electroluminescent (EL) wire, tape, panel, chasing wire, and bendable wire to let your project glow!

Use RealVNC to connect to your Raspberry Pi to control the graphical desktop remotely across the network.
