My RPi5 arrived yesterday. It took a while to get going.
For now I am just running a basic setup.First impression:
Things got - as expected - a bit more complicated with this device and
the new RpiOS (Bookworm). I've got a lot of tasks on my todo list.Power:
We had a discussion about the PI5 5A power demand over here a while ago.With SD-card and a basic boot and clock setup, I see around 750+mA short term peak
during boot and around 550mA @idle. Which is very close to the PI4. The community thinks it should be less for a modern chip. The RPI designers response was something like "give us some time, Rome was not built in a day". OK. That's RPI world.
Booting from SSD via USB-Sata cable I had to add around 200mA to the bill.The power chip seems to limit USB current to 600mA on non-compliant power supplies.
You can disable that safety limitation manually in config.txt (I did) if you know how.
Temperature:
@1500MHz and the GeeekPi passive cooling case I run @35°¢. That's "cool".NVME:
3PP NVME HATs are available soon from Pineberry. A friend of mine ordered a couple of them. I am not sure though how the cooling is supposed to work with these HATs.
Attaching them on top is not what I'd consider a good idea.
Bottom line.IMO the PI5 HW and SW is not a finished product yet. The nitty-gritties work though. And basic audio will also work.
From the PI4 we know that it took the foundation quite some months (almost a year?) to get the PI4 fully under control.
There's some light at the end of the tunnel...
What I already like is (1) the reasonable power consumption and (2) the rather low temperature. Better than expected.
For us audio folks there's IMO no rush to run the upgrade. Quality HW and SW/firmware and documentation is what's needed for a stable audiophile audio operation. Beside that all major audio-RPiOS providers need to get used to PI5 and Bookworm. That'll also take a while.
Let see how things develop. I keep you posted about my learnings.
Enjoy

I am still waiting for delivery. Your input will be a help when mine arrives. I just ordered a 4 gig model.
I received an email earlier this week from my vendor saying they received a batch and that mine should ship next week. I'm not convinced that there will be any sonic improvements over the Raspberry Pi 4 units that I presently run so I ordered the RPi5 with 8GB in case I need the extra RAM for purposes other than audio.
I hope they are not full of it and stalling. I pre-ordered mine from the Pi Shop. When the 5 was now available mentioned here. I got the order confirmation on 10/2/23
Looks like RPi5 4GB units are ready to ship the week of November 27th according to this email I received on Sunday November 26th. BUT.... the 8GB units are further delayed. Good thing I'm not in a hurry as I ordered the 8GB RPi5.
On November 26th, 14:06 MST PiShop wrote :"We are truly sorry for the extended delay. After battling many obstacles, the inventory of Raspberry Pi5 boards and accessories is finally coming to our doors! We understand it's not as early as we all expected it to happen. Our team has done its best to prepare and is ready to ship all pre-orders as soon as possible.
With our current inventory, we should be able to ship all pre-orders containing the 4GB version this week. We are hoping that the Pi5 with 8GB will follow very very soon and we'll be able to start shipping those the very next week.
We really do appreciate your everlasting patience and your support during this time! Our whole team will do our best to make sure you can finally start tinkering and start brand-new Pi5 projects.
Your dedicated PiShop.us Team"

I got the note today. We will see if they actually follow through with the shipment of my 4gig soon. I hope they get the 8gig units in shortly. Prime weather to stay inside and play with a new toy.
Finally !! The 4GB units shipped first and it now appears that the 8GB units are making it out the door.
Good news. Yes, I got mine and have played with it a bit. It keeps telling me my power supply does not have the 5 amp capability. I can't try streaming with attached DAC and USB memory source.
I found this on the interwebs:
"The total power drawn from the four USB ports on Raspberry Pi 5 is limited by default to a nominal 600mA; this limit is automatically increased to a nominal 1.6A when the USB-C PD Power Supply is detected. "
That's crazy. I did order a 5 A unit but the holidays are slowing things down. I guess I am playing along with the claim the 4 A supplies are not adequate. The unit does seem faster over the Pi 4's I have.
I could be wrong but a "USB PD Charger / Supply" might be needed. There are several with various power ratings on Amazon for powering and charging tablets, phones, laptop computers.
What is a USB PD charger?
A USB-PD charger is a charger that supports the USB Power Delivery (USB PD) standard. Compared to traditional USB charging technology, it can provide higher power output and faster charging speed.
Features and advantages of USB PD chargers
New generation USB PD chargers fully integrate Quick Charge to satisfy quick charging needs. In addition to supporting various output voltages and currents, it can also support various 3C devices such as mobile phones, cameras and notebook computers simultaneously. This makes the areas of use of PD chargers more and more extensive. The following are the three main features of USB PD chargers, and the advantages that derive from these features:
1.Meets the outputs of various powers:
It can mainly be divided into five power specifications: 10W, 18W, 36W, 60W and 100W, and four voltage specifications are used: 5V, 9V, 15V and 20V. Different power outputs can be provided according to the requirement of connected devices, to realize more efficient charging. Currently, in order to unify the specifications, USB-PD chargers all adopted the Type-C connector; not only are the specifications of connectors unified, it can also support more devices.
2.Smart power management functions:
Power output can be adjusted according to the requirements of different devices to improve charging efficiency and prolong battery life.
3.Supports multiple power modes:
Able to support power modes including PPS, APDO and QC, and compatible with the quick charge needs of different devices.
I pre-ordered mine from the Pi Shop and received my order confirmation on 09/29/2023 so just a couple days before you. According to an email I received from Pi Shop last week my RPi 5 should ship sometime this week. We'll see. I'll post here again as soon as it arrives.The selection of cases for the RPi 5 is a little limited right now from what I've seen on Amazon. They exist but not quite what I'm looking for. There are several dozen great cases for the RPi 4 so I expect to see more for the RPi5 before too long.
