Pi5: 5V 5A USB-C??? There is now 45W USB-PD (@15V) that would be compatible with generic PSUs but they went proprietary with 5A@5V.
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.
