Pi 5 sucks massive balls.

They now require a special power supply for it to work else it just crashes under load. Their use of USB C is insanely confusing because it doesn't work with any normal USB C psu.

This power supply costs 15 bucks which conveniently isn't included in the price. Also a heat sink that costs 6 bucks.

Also they stuck with micro hdmi which sucks. (even more special accessories needed)

The required accessories almost cost as much as just an old pi.

I hope the community jumps over to Rockchip based boards soon. Pi has taken the communities open source efforts and spit in their face.

Risc5 is also interesting but that seems to be a far bigger task since it need recompilation of a lot of existing stuff

Wow, at the start of this comment i thought you were just being overly negative, but one by one, each point crushed me a little more. it's so sad what's become of this once great little product. The special power supply is a complete and total deal breaker for so many reasons. that eliminated so many use cases for me. And the lack of a standard hdmi port (or even usb c video output) is just the shtty cherry on top.

Yeah power seems like such a small thing but for an SBC it's a pretty big deal.

The power usage is also pretty crushing for it the Pi's usage in hobby Robotics. Finally we have some computing power but now it's unusable because how are you going to get 5V5A from a powerbank? We could power the Pi4 from a decent USB C supporting powerbank, But this is no longer the case for the Pi5.

If they supported "normal" USB PD then at least a powerbank with quick-charge support (9v3a) would work and give you the same total 25W wattage. And the PD USB chargers would have been way cheaper because 9v3A get mass produced. This 5V5A is some Apple tier of "propriatary" standard and I really wonder why they did it.

But it does support usb pd, starting with pi 5, you can use any usb pd power source, so long as it can provide the needed wattage

I refuse to admit 5v5a is USB PD. This is like USB3.1gen2by4 Rev 9001

USB PD was meant for

15w = 5v3a

30w = 9v3a

45w =15v3a

60-100w = 20v3-5a

Phones that wanted to do it different made up their own name with blackjack and WOOX charging. I don't need the Pi foundation single handedly screwing this up.
