Raspberry Pi400


Latest from Raspberry is the RPi 400, it's a faster (1.8GHz) version of the 4GB model, slotted inside their keyboard, at £67, it's a great piece of kit.

Looks good to me too.

For those that are of that age... reminds me of the Commodore 64 and other "keyboard" computers.

How long before the 8Gb variant?

Looks very, very good, though for some situations a cap will be needed for the GPIO pins.

As a user of mc, (midnight commander), I notice the RPi400 keyboard has an ins key, whereas the regular keyboards don't, & that was one point I mentioned when they brought it out originally, so it seems like they listened, that's good.

(Mine should arrive this week - I missed the first batch.)

Nice. Though it pained me to write that since the availability and functionality GPIO pins are one of the best things about the Raspberry Pi. However, with just this form factor, it is likely to see a lot of use in classrooms and maybe call centers or other places when the pins could easily come into contact with metal.

I'm sure there will be an number of 3D printer files available for a suitable cover shortly.

If you are in a hurry, you can buy 'dust plugs' on the internet, but I'm reading that the pins are slightly recessed, so might not be needed, & if you don't plan on using them, a bit of (electrical) tape over them should suffice.

I'll use some ribbon cable, but the concern is for some lab environments.

Received my RPi400 today, & on looking closely at the GPIO opening, I think it would take quite a bit of bad luck to make contact with the pins, in normal use, they are set back about 1/10th of an inch, & are about 1/4 inch above the surface the keyboard is sitting on, (I won't be worrying about them).

First impression was that the keyboard keys looked a bit 'fragile', but having been working with it for several hours, they're fine.

I've tried mine running from micro SDHC cards, & booting from external USB3 HDD, (SSD will be tomorrow, but don't see it being any problem).

Seems to be a nice little bit faster than my RPi4B/4GB, programs appear to load a bit faster too.

All in all, I like it.

Sweet. It sounds like they have made another winner with that model. Myself, I am still waiting to order. The layout I want is not on the shelves yet and the second choice layout is constantly sold out. So I'll have to be patient.

I'm glad to hear the GPIO is recessed a bit. Maybe there is not a real need for a cap then. It's supposed to be noticeably faster than the 4B but with that model I find that the hold ups are all due to the microSD card. I don't do audio, video, or image editing so if the storage is solvable, it'd be a good desktop replacement for many situations.
