Well I just went to read several topics:

In resume:

-yes I do need the wifi version of the CM4 or CM5 as the uconsole cannot connect to the CM4-CM5 pins for that.

-CM5 is faster but drains battery faster, you can cap the cpu clock to fix this.

-The bottleneck is not the cpu but the os access as if you use the SD to store the OS, you depende on the reading and writing speed to the SD, if you buy a expensive one they can go up to 300 mb/s or maybe higher but those ones are extremely expensive.

-Storage is a better option here but you need to board to flash the CM4-CM5 and then you do no ask for a lite version.

- SSD is better option apparently.

- Any upgrade makes the device to consume more battery so… time to check the energy storage stuff.
