Hello,
I noticed that the AutoPi TMU 3rd edition says that it is:
The AutoPi TMU Pi3 ships with the Raspberry Pi3 Model A+, but has been designed for the future. This means that it is easily upgradeable to the Raspberry Pi 4, if you need even additional processing power.
I guess I was wondering how this worked exactly. Do I just buy a Raspberry Pi 4, take it apart, throw the new one in, put the SD card in the new one and bada-bing bada-boom I’m done. Everything will just fit, and all the things will be aligned and I don’t even need a new face plate? I’m concerned about the about how the chassis will work with the Raspberry Pi 4, since it looks like this is a model A, but there is no Raspberry Pi 4, model A.
