Learn the difference between 3.3V and 5V devices and logic levels.

Learn how to use serial I2C and SPI buses on your Raspberry Pi using the wiringPi I/O library for C/C++ and spidev/smbus for Python.

Not working as expected? In this tutorial, we will be exploring a few general troubleshooting tips and possible solutions that frequently come up with SparkFun's Technical Support.

Come look at the basics of working with Field Programmable Gate Arrays.

Vernier Photogate Timer -- using the Serial Enabled LCD Kit.

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 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.
