onboard processors for lymow one MCU

User experience

I read an old post where a user said that with an older firmware version, you could log in via SSH with the password "limow" (which was then patched on the fly). he could have copied the entire source code and distributed it (but that's another story). So, using this as an excuse, I watched a YouTube video of the MCU assembly in slow motion and found a couple of interesting things.

The system has two onboard processors.

STM32H735AGK6

AT32F403ARCT7

Quick Comparison

Features STM32F407ZG AT32F403ARCT7

CPU 168 MHz 240 MHz

Flash 1 MB up to 1 MB

RAM 192 KB ~224 KB

So, IMHO we are waaaaay under the firepower to do "real" object recognition, It would be interesting to see if there is something in the camera module (which is covered by an aluminum heatsink), but for now I haven't been able to find a video showing how that is assembled.
