There Is A Raspberry Pi 400 Hidden In This Keyboard

Just Add A Monitor And Boot

The Raspberry Pi 400 is not quite the cyberdeck you are hoping to upgrade to once Cyberpunk 2077 finally arrives but for now it is the closest thing you can buy, and it is only $70.   In this tiny little portable keyboard is a a 1.8GHz Pi 4 ARM Cortex-A72 CPU, 4 GB of RAM, Bluetooth 5.0, 802.11ac wireless, gigabit ethernet, dual micro-HDMI outputs, a microSD port and a 40-pin Raspberry Standard IDE-cable connection.

For peripherals, you will have two USB 3.0 ports and a single USB 2.0 port to populate; while there is a single USB-C port it will be used by the 5V power supply.  If you don’t already have various pieces to required to make the Raspberry Pi 400 sing, for an extra $30 you can get the full kit which includes a nice USB C power supply, a Raspberry mouse, a mini-HDMI to regular HDMI cable, a name-brand SD card with the Raspberry Pi OS already installed, and the Official Raspberry Pi Beginner’s Guide.

Of course, Hackaday did not take long to tear the board apart and they discovered a hefty aluminium heatsink attached to the A72, which not only handles the heat produced by the processor but have made them curious about the overclocking abilities of this keyboard computer.

Check out their review and follow the link to buy one if you find yourself thinking of things you could do with the Raspberry Pi 400.

There are two packages for the Raspberry Pi 400: the basic and the full kit, for $70 and $100 respectively. The extra $30 gets you a nice USB C power supply, a Raspberry mouse, a mini-HDMI to regular HDMI cable, a name-brand SD card preloaded with Raspberry Pi OS, and the Official Raspberry Pi Beginner’s Guide.

    I’ve been thinkin alot about this toy since I first read the article yesterday on hackaday…… It brings me back to the long long ago days of cheap(ish) computer in a keyboard “Micro Computers” from when I was just a wee little one, the VIC, TRS, ZX…. so many others, it seemed like every other home in the neighborhood had one that were in no way compatibale with eachother and only the coolest homes had Atari. You’re still making sacrifices to do it cheaply all in one fan free, but it’s still an impressive amount of power packed into that keyboard, and innovation has lead to a SERIOUSLY impressive apps community with plenty of awesome games, SHIT you can emulate some sick consoles on it even the dreamcast pretty well. It’s very cool that the PI is still evolving instead of just fading away after the kickstarter. Neet.

    Also, I want one, I would have one on the way now, buuuuutttttt, just like everything my childhood, NOT ON SALE IN CANADA!!!!!! The more things change, eh?

    Also I gotta say, The teardown surprised me, I expected a standard PI with extensions for the ports in a custom enclosure (like all the purchasable home brews) but NO, it’s a new board, made specifically for this device. That’s kinda cool, I wonder if they are planning to eventually sell this custom board for DIY projects….. I know it’s silly but I could see making a mini commodore 64 that ACTUALY works exactly like a 64 with this board, even down to attaching a tape drive with the extension port……. not like I’m actually going to do that but it’s a thought!
