I just received the hopefully-final-for-a-while Rev. B Ver. 1.0 PCB from PCBWay today. I hope to have one populated and tested over the weekend. Then I can start mounting the board and sensors inside the vending machine.

After this, just need to set up the Motioneyeos camera to read GPIO and find a good location to deploy it. One Dutch guy who made a similar, though much larger, machine was able to get it placed in a zoo. Once I have everything together I might see if Artis would be willing to do this with mine.
