Feels like they had to develop around their component shortage. Very weirdo microcontroller/DSP mix.

It may even be a good thing, from a PoV of learning resiliency and adaptation to supply chain changes. They probably ended up very hard to disrupt.

I've seen an Orange Pi 5+ in a drone, which I wrote the upstream DTS for conincidentally, Raspberry Pi, etc.

Despite Opi5+ having sophisticated ISP and camera interfaces, they just used some USB/analog camera capture card. Probably because if you're using generic interface that just works, you can just throw in any SBC in that has some so-so working Linux build somewhere so that USB and gpio/i2c/spi or any of these generic interfaces work on and you're golden. Your other software can then stay the same, because everything that uses these interfaces from userspace is well abstracted away from platform details by Linux and works identically across all SBCs.

Most of the components are from Western countries. Seems like a lot of leverage.

Bosch is a surprise, I'd have thought they'd be addressed by now.

Bosh is off the shelf car fuel pump. US AD9258 on the other hand might be covered by EAR or ITAR.

Raspberry Pi driven drone. What a life.
