[@СергейВладимирович-б9з]

They do very wise decision not to use wifi built in board. Cheap wifi assembly tends to have different quality issues - either closed source drivers that works with tons of trubles and have conpatibility issues, or issues with recieving/transferring physical module, or issues with decoding/encoding chip or errors in frimware. So if you need wifi connection, they supply this device with additional standard usb hole, where you can insert any favourite usb wifi plug and have wireless connectivity experience. Very good, wise and lucky decision - user have freedom of choice - there plenty different usb wifi plugs on the maket.

6:40 Nope, the 400 number is not an homage to the Amiga 500. It's an homage to the Acorn Archimedes 400 series, which was the power user version of the Archimedes (the low-end version was the 300 series). All the Raspberry Pi names pay homage to early Acorn computers (the BBC Model A, Model B, Archimedes, etc.). The ARM processor was originally the Acorn RISC Machine CPU -- the first 32-bit desktop RISC processor, released with the Acorn Archimedes.

Also, since those connectors suck and almost any device uses full size HDMI or uses USB C for Video (that connector is around a billion times better then Mini/Micro HDMI), nobody got those fucking Cables/Adapters on hand. No, less is not allways more. They really got more then enough space for at least one full sized HDMI on there. Or do it at least over a USB C port, that is actually a good connector. The recourses argument is pretty week btw. The difference between Micro and fullsize is very small, it basically didn't matter. But if those tiny amounts of material mean something to you, think about the adapters to fullsize people need to buy.

Thanks, Jeff, your video of how to get the keyboard off was very helpful. This work for the Raspberry PI keyboard as well. This comes in handy if you need to switch the keyboard language or have a damaged keyboard. The Pi keyboard and the Pi 400 keyboards are compatible. Also your selection of the tool to pop the seams on the keyboard is spot on. I have not found a better tool.

[@Sebbl3]

I wonder why they didn’t use the new compute module. With that, it would be upgradable in the future.

[@zuryan]

I agree. the first thing I thought is that it's cheaper to produce the Pi 400 as a single part but they're making both anyways so it shouldn't matter.

[@MarkEmeryPhotography]

Imagine the physical abuse some Pi400s will get from frustrated kids. I think a single board is better.

[@electronics-girl]

@@zuryan There's still the cost of the connectors, on both the Compute Module and the hypothetical main board. The Pi is cheap enough that that sort of thing matters.

[@zuryan]

@@electronics-girl the compute module is already being sold with the connectors. so all they need is two connectors on the keyboard PCB. the only two reasons I can really think of is 1st, it technicly not being a "single board" computer anymore, and 2nd the compute module remains not as easily usable by tinkerers so that way they can don't run into stock shortage for industrial use as easily.

[@JeffGeerling]

It also saves on the overhead of adding a bunch of extra jumpers/cabling to get the GPI, power, and HDMI plugs on the back of the unit. I think this design was the easiest way to get the whole thing in the same footprint as the Pi Keyboard.

The key for this particular case was rigidity. Unfortunately all my guitar picks on hand were too flimsy, and my normal spudger and credit card were both slightly too thick to fit into the gap. But yes, a good solid guitar pick would probably be perfect, and result in less risk to my digits!

[@bufordmaddogtannen]

This is exactly the form-factor folks need for making Raspberry Pi 4 ‘blade’ clusters as the key ports are all on one sides for various cluster mainboard configs: - headless network boot config - ethernet (for pxeboot), power, gpio (serial, i2c, gpio to trigger reboots, etc), - boot with storage - ethernet (for pxeboot), power, gpio (serial, i2c, gpio to trigger reboots, etc), sdcard option, and USB drawn out for USB stick, usb3 sata, usb3 m.2 nve, and other peripherals I also see this slim form-factor helpful for projects helpful for those where a “3×5” style board cannot fit. If the Raspberry Pi foundation or licensees do not release this form factor without the “keyboard wrappings”, makers will gut the keyboard which will be landfill plastic eventually. And that would be bad, m’kay. Jeff, please provide the Pi Org some feedback to sell this mainboard form-factor on its own. They could even optionally leave the keyboard ribbon adapter off.There is a demand for this configuration.

FINALLY, a usable Board with all external Connectors on one side. I got tired trying to Integrate Pi's in Systems and routing the HDMI-Cables with Adapters to the back. All I need now is SMT for external antenna and a internal USB-header.

[@keithmiller9665]

OK, after playing with this in the UK for several days doing lots of ffmpeg based h264 / 265 video transcoding I found that the Pi 400 can run up to +20C compared to using an Ice Tower with a regular Pi 4 4GB, e.g 66 C v 47C. Now most people don’t run video transcodes for hours like me. I ran ffmpeg libx265 CRF 20 for 15+hours (0.043x with 41 mins input file). So definitely usable from a temperature if not performance perspective. On the downside I had a boot USB 3 SSD connected and found that like the Sinclair ZX81 from the early 1980s the connector comes out far too easily thereby freezing the Pi 400. It is crying out for an internal storage option. Just move the keyboard and the USB 3 SSD interface link is interrupted. Sticking with MicroSD might be a better option.

[@sp0el]

When I first saw it, for whatever reason I was sure it will have a compute module 4 inside. New PCB makes more sense though, as it definitely is cheaper than separate I/O board. Can't wait for new Pi-laptop builds with this new form factor!

With the DSI port being removed, there won't be any laptops based on this hardware.

[@dorjeboleskine4115]

Fantastic teardown, mate! 😊👍

[@marceloafgomes5767]

Something I've NOT noticed at first is that it lacks the CSI and DSI connectors. I guess it makes sense to leave out the DSI in such a design, since it already has two HDMI outputs; but maybe people would want a camera, even if only to use a videoconferencing app. Also, a microphone input would be a great addition. Of course one could add both the camera and the mike with a single USB port, but it would be nice if we could use whatever interface had become available by cutting out the DSI port to add a sound digitizer, and still keep the CSI port for a Pi camera.

[@bayzano]

[@Scrogan]

That’s really neat, didn’t know they made one. But I’d never use the power of a pi4 unless I was trying to make it run proper CAD software or whatever, so would probably prefer a cheaper one with a pi3. A trackpoint in the middle of the keyboard would be a nice touch.

[@SharkLasers380]

[@Daaanin]

Kind of sad to see its not compute module based. Otherwise it's rather cool.

[@JeffGeerling]

It would be really nice to have that, though I'm guessing the main culprit is the thinness-having a daughtercard to carry the CM4 would make it harder to fit that giant heat sink inside, and it seems the heat sink is necessary to keep the thing from overheating (which it does very well in this case). But it would be very interesting if someone could build a little carrier board for the CM4 that would fit inside (with some modifications to the heat sink).

Hey Jeff, my Pi 400 is the computer I could afford right now. When I get something more powerful, is there a way to use the pi 400 as a keyboard for it? (to reduce cost, clutter, and e-waste)

[@ricksarvas6563]

I'd been wondering about the formfactor of the actual PI inside the keyboard. I guess I was expecting to find a Raspberry Pi CM4 attached to a backplane providing all the IO ports. I did not expect to see an all new board design.

Red Shirt Jeff is great. Maybe he should have his own video. He could really do a destructive review on sub par hardware.

[@JeffGeerling]

Red shirt Jeff let me know I should like your comment.

[@ben_r_]

Thank you for showing this! Needed to know how to open this thing so I can try and sway the white keyboard for the black one!

[@JeffGeerling]

Just don't use a knife like me; find a spudger or guitar pick!

[@ollllj]

yes, this is definitely an in joke reference to the [commodore amiga 500] 25 years later, the 1,4 mb floppy drive just got replaced by 64000 mb microSD, and it has 4000k ram instead of 64k ram, and the ports got more universal and easier to use with plugNplay , but the general purpos of "learn to code in a basic language, play some games and maybe attach some peripherals with blinking LEDs, and maybe write some html and netwrk protocol to even use this to host a webpage", is identical. This one supports webgl3 and has half decent specs for THAT, which is possibly the best use case for teaching anything easy of universal utility and with LOTS of "what you see is what you get" coding appeal. Via webpages like shadertoy, you can even code FM-synthesis in opengl/webgl rather easily.

Hey nice video! Hadn't heard of it till now. Well done.

[@Minecraft-3699]

so.. i look for both the raspberry pi 400 and the game teardown like 2 hours apart.. and the algorithm gives me this

[@zadekeys2194]

I use various guitar picks to open such things. Works very well

[@Jarajesh]

The first video where I saw somebody open & put things back in place so fixable

[@Kps117A]

This is going to be so cool for those DIY Raspberri Pi Laptops.

[@RichardHaydenuk]

Love that shaping noise

[@leepspvideo]

Great job Jeff. 👍🏻 The Pi 400 laptop will likely be coming soon.

[@rickriffel6246]

Any tempting thoughts of clustering and overclocking the Pi 400 boards?

[@Ojisan642]

You should get a set of plastic prying tools. The metal tool will work but could damage the plastic components. You can get a set of prying tools for like $2-5 on sites like Newegg.

[@hikaru-live]

If they put CSI and DSI connectors back, we can get a motherboard for a Pi-based ultra thin laptop. They also would need a GPU driver for a DSI to eDP chip since most laptop displays uses that interface. Also includes should be an internal USB 2.0 hub for a trackpad, USB sound card for implementing internal speakers and the keyboard.

[@danswope]

Red shirt Jeff is my spirit animal. But legit that joke keeps getting better lol

[@SolaLupus]

4:47 That's not true, pi 4 (and also pi 3b+) both have ethernet magnetics with support for poe, it's just integrated into the RJ45 jack itself. The transformer middle taps needed for POE are routed to the 4 pin header next to the connector. You just need to attach to it the POE hat or other POE power module. But I agree with you, that they missed the opportunity to implement POE into the PI 400.

[@dlbower1956]

I choose to believe that it is an homage to the AS/400. - The one I told IBM they should have built, but they didn’t listen to me, and now the 400 sits in the corner with it’s cousins, the PS/2 and OS/2. Long live the Pi!

[@bsvenss2]

Great video. Well worth a subscription.

[@davidanthrope6084]

+1 for including the bloopers :-) no seriously, thank you and I would +more if I could!

[@keithmiller9665]

No mention of audio jack in any of the early reviews. I checked the specs on datasheets.raspberrypi.org/pi400/pi400-product-brief.pdf and there does not appear to be an audio jack. So sound is HDMI only? Can you confirm Jeff?

[@JeffGeerling]

Yes, no built-in audio jack or composite video. Apparently since the space was lacking, they dropped that instead of something else. I am using audio through HDMI on my monitor, and most (all mine at least) have at least a 3.5mm audio passthrough, if not built in speakers. For those that don't, there are HDMI audio splitters, though that's an extra expense.

[@keithmiller9665]

Thanks Jeff for the confirmation and HDMI audio splitter tip, ordered from Amazon UK ;-)

[@noxious_nights]

So it's just an elongated Pi 4 inside a keyboard? Damn that's cool.

[@DoRC]

I was really expecting a compute module in there. I'm surprised they spun another board that was probably cheaper to do it that way.
