Yes exactly, when looking for it I find only Arduino kits. Some time ago I got interested in pine64, was reading a while and bought a soc board plus some stuff around it (like a touch screen and emmc storage). Turned out that particular board didn't come with the display output and to install a system on emmc you need an UART Adapter, so I ended up buying more stuff, which I was missing. Don't want to do the same again ^^
With esp32 I have the problem that there are so many different and I don't see how they differ (except the price)
