To make a start with Drone the most affordable, the following reference hardware was selected for this book:


  • 2× STM32F103C8T6 development boards (Blue Pills)
  • CH340G USB-TTL converter
  • Female-to-female jumper wires

And optionally:

  • 2× Angled 40-pins 2.54 mm header - Blue Pills already come with straight pin headers


Usually Blue Pills come with not soldered pin-headers, except the SWD header. If you don't want to solder, you can twist the wires like this:

Twisted joints

Here are the Blue Pills soldered with the angled pin-headers:

In the next chapter we will show how to convert one of the Blue Pills to a Black Magic Proble.
