anyone into this stuff? Arduino for ST Microelectronics stm32 Arm Cortex-m3, m4 mcus
it started with the leaflabs maple

^ do note it is a group of enthusiasts not commercial

it started from here
and evolved over several years since 2015 into the 1st 4 links

the boards are decently cheap, this is a clone of the maple mini by baite in china (you can find them on ebay too search for stm32f103, u'd normally see STM32F103C8T6 or STM32F103CBT6, note C8 - 64k flash, CB (>B< not 8) 128k flash, that flash keeps your arduino sketch and runs from it
^my own personal preference is to start with this as it is based on similar design of the original maple mini, and this normally has the bootloader pre-installed, otherwise as a newbie, u'd need to learn how to install a bootloader e.g. https://github.com/rogerclarkmelbour...mer-from-Linux and the vendor bother to use a CB (128k) the even cheaper ones may be simply using c8 (64k)

there are others like this one from olimex
i think www.element14.com stock them

then on ebay if you do a search for stm32f103 you could find many us$ 2 boards with it (commonly nicknamed blue pill around the web)
for many of these u'd need to install the bootloader yourself


videos like this sell by itself, the faster one is stm32 (stm32f103)
the other one is an atmega328 common to many of the low cost arduino boards such as uno

Yes, it's a very impressive yet cheap board.
