I see one one M.2 M Key facing downward, so presumably it will hold the cellular modem on top of the battery.
What doesn’t make sense to me is that the second M.2 B Key is facing upward, so the M.2 card holding the Wi-Fi/Bluetooth will extend beyond the top of the phone.
Am I seeing this wrong?
EDIT: Yes, I was seeing it wrong. See romnasko’s image below.
Another detail in the video that surprised me is that Faerber mentioned that there will be a STM32L432KC, which is a 80MHz Cortex-M4 for reading the smart card and they want to create free firmware for it. I didn’t think that it would be necessary to have another processing core just to read a smart card. I would have expected that the cores in the SoC to be able to handle that, but apparently not.
