One of these boards you can get for cheap from Asia. The other two ones are DIY designs I made myself. And the main question for this video is whether they pass EMC guidelines which are super important when you want to sell your board. We will be testing conductive and radiated EMC. And at the end I will show you how you can fix EMC problems of such boards. Let's get started!
