The Blue Pill is a wonderful little board, and my first choice for many projects requiring a small and very low-cost µC board. Especially with PlatformIO’s excellent support for it.
Even for retrocomputing – the hobby of emulating old computers from decades ago – a Blue Pill can be used: see my recent Turning a Blue Pill into a Z80 article for an example. This could easily be extended further: adding more (external) RAM, flash, an SD card, etc.
