#RaspberryPi – Raspberry Pi 400,

Hi !

It seems that it was yesterday when I wrote about the amazing and new Raspberry Pi 4, and it was on February ! There was a lot of news since February, however the Raspberry 400 is a huge milestone.

From a hardware view, is a faster device, that’s cool. However I really like the all-in-one format:

Raspberry Pi 400, a compact keyboard with an ARM-based computer built in.

Start is super easy

• Add your SD card with your OS image
• Connect 1 or 2 monitors using the 2 micro HDMI ports
• Power the device
• Optional, connect a mouse
• that’s all !

The specs are super cool:

• Broadcom BCM2711 quad-core Cortex-A72 (ARM v8) 64-bit SoC @ 1.8GHz
• 4GB LPDDR4-3200
• Dual-band (2.4GHz and 5.0GHz) IEEE 802.11b/g/n/ac wireless LAN
• Bluetooth 5.0, BLE
• Gigabit Ethernet
• 2 × USB 3.0 and 1 × USB 2.0 ports
• Horizontal 40-pin GPIO header
• 2 × micro HDMI ports (supports up to 4Kp60)
• H.265 (4Kp60 decode); H.264 (1080p60 decode, 1080p30 encode); OpenGL ES 3.0 graphics
• MicroSD card slot for operating system and data storage
• 78- or 79-key compact keyboard (depending on regional variant)
• 5V DC via USB connector
• Operating temperature: 0°C to +50°C ambient
• Maximum dimensions 286 mm × 122 mm × 23 mm

I am really looking forward to test the GPIO pins on the back of the keyboard. I have several hats, and connectors for this, so I’m sure that we will see some adapters in the near future:

And I really like this analogy from FastCompany (see references)

Of course, the computer-in-a-keyboard concept isn’t new. As The Verge notes, the Raspberry Pi 400 is a throwback of sorts to classic PCs like the BBC Micro, ZX Spectrum, or Apple IIe, and some vendors such as Asus have tried to revive the concept before. But with Raspberry Pi’s low pricing and its emphasis on education, now might be just the right time for a revival. The only question is when Raspberry Pi takes the next logical step and makes a full-blown laptop.
