crypticcelery 🔙 EH23#AskFedi: If I was looking for a very small microcontroller (think like less than 5x5 mm), I would guess there are things that exist, right? Any pointers / suggestions?
you're all idiots@crypticcelery I use the STM32C011 when I need small. It's 3×3 mm in the 20 pin QFN package. Bit low on memory, 32k flash isn't enormous when writing ARM C++ code, 6k RAM. 15 general purpose I/Os if you keep the reset and SWD pins.
