I agree that the 3B+ was the best Pi but for other reasons:
Was not even thinking about that. Implementing USB-PD is so easy these days. Basically just putting a chip there who handles the PD and then a step down(or whatever) converter which they already have anyway. (See ebay USB PD trigger for implementations)
That is so dump.
Talking about hardware flaws, i think they even fucked up the USB-C implementation on the PI 4. They put the resistor on the wrong pins or somthing. Dont remeber exactly.
I think operating at 5V input might be a technical constraint for them. Compatibility revisions for existing hardware are a lot more difficult if the input voltage is 9x higher. Addressing that isn't as easy as slapping a buck converter on the board.
Not saying requiring 5A was the right call, just that I can see reasons for not using USB-PD.
We are not talking about 9 times higher. 3A at 9V would be enough.
I am currently looking in the Docs and it is really confusing. It states that the PI 5 has a PMIC on board but still saying it boots up only when the 5A is present... So not sure what is going on here.
And looking at the PD 3.1 standard it looks like 5V 5A is actually in the spec in the new Version...
Will have to get my hands on the new PD 3.1 spec.
They used 1 resistor for CC1 and CC2. The fix and correct implementation was to use one resistor per CC-line (two in total).
Picked up a laptop with a busted screen $30 cheaper than the RPI 5. 1135G7, 8gb upgradable ram, m.2 storage, wifi, bluetooth and a battery.
Raspberry pis' were great early on, but their appeal has quickly diminished in my eyes considering used hardware options that are available now.
Size would be the one redeeming quality of a raspberry pi for me, my headless laptop is thin but takes up substantially more space.
