I'm wondering now what these machines might be good for as parts. After this company goes belly-up, surely these machines can be had for pennies on Ebay. What can we do with them?
They have that absurdly over-specced ARM processor, with convenient USB terminals on the PCB for flashing it. I'm sure you could make them useful.
Calling an STM32F407 absurdly over-specced is hyperbole. It's just a 6$ micro controller, not a smartphone class SoC like a Snapdragon.
They probably need it to do the QR code scanning and IoT DRM thingies.
It is certaily over-engineered. All the stuff mentioned can probably be done using an 8bit Atmega.
