The STM32L443CC 'Bluepill+' Following up from the work I did on getting Ada going on a Bluepill. http://www.hrrzi.com/2017/11/ada-on-2-ebay-bluepill-board.html Is a Bluepill a fixed entity? Looking at the SoC the Bluepill uses we see it is a Cortex-M3 running at 72Mhz with 128k of flash and 20k of ram. There are newer STM32 chips all the way out to Cortex-M7's. I have this tool from ST called the ST MCUFinder. You can screen all their parts by different parameters. I had already hacked Ada onto the STM32L432 for the Make-with-Ada contest last year so the L series was still quite fresh in my mind. So looking at the package the STM32F103C8 on a stock bluepill was there a newer, pin compatible, STM32 cpu across the family that could drop in and work in place of the original? I will spare dear reader the suspense, indeed there are a bunch of parts that have the same footprint. The candidate CPU for Bluepill+ STM32L443CCT6 That part uses a Cortex-M4F, runs at...
