Breadboard, yes, but if you&#x27;re making your own PCB, I&#x27;d argue that SMD for the micro is easier (not to include BGA, but everything with perimeter pins, I think SMD is easier, even for the home hobbyist).<p>For SMD-only parts, there are SMD to DIP adapters readily available to let you use them on breadboards; for relatively low-frequency digital work, there&#x27;s no problem using them, so being available in through-hole isn&#x27;t a practical advantage.
