Before we proceed, short clarification. Legal background of AnyFC F7 flight controller from Banggood is
iffy. It’s not that BG ripped the design from Sami Korhonen (sambas). Sambas published design of his AnyFC under Creative Commons BY-SA. So, it’s free to copy this design as long as Sambas is referenced as author, and license is not changed. The problem is that “by attribution” part is not met. Sambas is not referenced as author on BG. Still, Sami wrote that he is fine with it, as long as boards quality is good enough.
Today I have something brand new to write about. Probably the first commercially available flight controller based on STM32F7 CPU: AnyFC F7 from Banggood.
