STM32

Has anyone here used an STM32 as a microcontroller for switching? The reason I ask is that JLC has a few as a basic part for assembly.

Just wondering how easy it is to program. I'm guessing you would need pins on the pcb in order to flash the firmware onto it.

ESP32 boards are cheap on aliexpress and wouldn't be much more expensive but can be programmed using auduino so might be a viable option instead I guess.

The ATiny doesn't have enough pins for encoders I dont think?
 
I've done a little bit of playing with STM32, but not much. They're not terrible to flash, but you have to be set up for it, including an ST-LINK or similar device.

I use ATTiny for my switching, JLC has a pretty good stock of them. ATTiny can also be flashed by Arduino which is a lot more convenient for simpletons like me that are too scared to learn a real IDE.
 
I've used ATTINY. Even if JLC doesn't have any of them as a basic part, as long as LCSC does, you're good. You'll just have to pay a $3 or so extra charge for loading the non-basic part spool on the pick and place machine.
