Asynchronous serial communication concepts: packets, signal levels, baud rates, UARTs and more!

A primer on digital logic concepts in hardware and software.

Introducing fundamental digital logic concepts and LogicBlocks

This tutorial will show you how to build a magnetic levitation circuit using common parts.

Because some of our boards need to be re-humidified after reflow, we decided to make our own humidor. This tutorial will focus on how to model a project in 3D and then fabricate it using a CNC routing machine.

The TFMini is a ToF (Time of Flight) LiDAR sensor capable of measuring the distance to an object as close as 30 cm and as far as 12 meters! The TFMini allows you to integrate LiDAR into applications traditionally reserved for smaller sensors such as the SHARP GP-series infrared rangefinders.

Learn how to wield the power of 18 channels of UV to NIR spectroscopy with AS72651 (UV), AS72652 (VIS), and AS72653 (NIR) sensors!
