Wio Terminal Makes Passable Oscilloscope

There was a time when getting a good oscilloscope not only involved a large outlay of capital, but also required substantial real estate on a workbench. The situation has improved considerably for the hobbyist, but a “real” scope can still cost more than what a beginner is looking to spend. Luckily, plenty of modern microcontrollers are capable of acting as a basic oscilloscope in a pinch, provided there’s a display available to interface with it. Combined with the right software, the Wio Terminal looks like a promising option.
