Posted on September 29, 2015 at 08:07One additional question. I'm planning to use it for a keyboard controller. Since STM32 MCUs come with bootloader, I don't really need a programmer, to get my firmware on it, right?

Posted on September 29, 2015 at 07:53Thank you for quick reply. Yes, now I see that ST does indeed explicitely feature some of the MCUs as working ''crystalless''. Good. Best regards
