I went looking for a STM32F042F4P6 dev board on Aliexpress yesterday. Such a thing doesn't exist!! There is the poor cousin, the STM32F030, but that's it. This afternoons project was to whip one up:Not much to it, just the basics plus a DIP switch and a LED etc. It's only 40mm x 22.5mm, so I had to place some hand soldered components on the other side to make it all fit:
There are eight to a panel and it's around A$12.50 for JLCPCB to produce five panels, so thats 40 small Dev boards I could make up. See you again in 3-4 weeks time.
