No.
No what?
3mm is greater than 2.5mm, how are the push fit cases like the RPi one and many Zero design suppose to work?

2.5mm is fine by me.

Or go smaller, go to 2mm.
Then anyone with 2.5mm can drill out for backwards compatibility.

I can't make 3mm smaller.

While the Pi could do it, a simple pi zero. And you could alter a text file, then say have them reboot the Pi and have it read the file when the program runs... ....

I believe you can bit-bang and use a software-serial on some other pins. But, I've never done it. (Unless you want to set settings, then you only need the RX from the GNSS module.)

Re: Netflix on Raspberry Pi 4

Use the Vivaldi browser and follow their instructions for the Pi with respect to Widevine.
There is a link above already.
Then log into Prime Video.

And play.

I expect you can do something similar in Chromium too.
