Eg you can get STM32G030 and similar at quite normal prices at LCSC (and thus JLCPCB assembly service, highly recommended over hand soldering BTW). OTOH stm32f030 (older and 2x worse in most respects) are way overpriced.&lt;p&gt;In addition to various esp32s (which have very decent sdk) you can easily get rp2040. You can also get a number of Chinese chips other than esp32 but good luck programming these.</text></comment>

The more important question is &amp;quot;at what price&amp;quot; though, because some of these chips are more than 10x more expensive than years ago.</text></comment>
