Green Pill

As mentioned elsewhere, the first STM32 development board I got my hands on was a so-called Blue Pill and it was a truly horrible experience. I do understand that some of these boards are sold cheaper than the price of a STM32F103 MCU, and it would be perfectly acceptable using clones if this was a well documented fact. Unfortunately, a lot of the vendors use clones which are labelled as genuine STM32's.
