DISCLAIMER: I know nothing about Pi development so I’m reviewing this as a keyboard PC. At the beginning of November 2020, it was announced that there would be a new Pi, the Raspberry Pi 400. Think of it as being a Raspberry Pi (or PC) built into a keyboard.
FEATURES Processor: Broadcom BCM2711, quad-core 64-bit SoC (ARM Cortex-A72 @ 1.8GHz). RAM: 4GB LPDDR4-3200. Connectivity: Dual-band wifi, Bluetooth 5.1, gigabit ethernet, 2 x USB 3, 1 x USB 2. GPIO: horizontal 40-pin GPIO header. Video & sound: 2 x micro HDMI ports. Multimedia: H.265 (4Kp60), H.264 (1080p60 decode, 1080p30 encode), OpenGL ES 3.0 graphics. SD card: MicroSD card slot for OS and data. Keyboard: 79-key compact keyboard. Power: 5V DC via USB-C connector.
CONSTITUTION
Processeur : Broadcom BCM2711, quad-core 64-bit SoC (ARM Cortex-A72 @ 1.8GHz). RAM : 4GB LPDDR4-3200. Connectivité : Dual-band wifi, Bluetooth 5.1, gigabit ethernet, 2 x USB 3, 1 x USB 2. GPIO : Connecteur GPIO horizontal 40-pin. Vidéo & son : 2 ports micro HDMI. Multimedia : H.265 (4Kp60), H.264 (décodage 1080p60, encodage 1080p30), Affichage graphique OpenGL ES 3.0. Carte SD : emplacement pour carte MicroSD pour l'OS et les données. Clavier : clavier compact à 79 touches. Alimentation : 5V DC via un connecteur USB-C.
KIT CONTENTS While you can buy just the keyboard itself (£68), I went with the kit (£95). The kit contains: • Raspberry Pi 400 • USB mouse • Power-supply • SD card • HDMI cable • Beginners guide book. The kit is of great quality. The mouse and power-supply come in their own little boxes inside the main box. The book is in the bottom of the box and the keyboard itself is on the top. The keyboard is a nice weight. I hate keyboards that feel like they’re empty, but since this has some meat inside it, it’s got a good heavy feel to it.
STARTUP The 400 has no on/off switch (which is a bit odd) so, as soon as you plug in the power-supply, it’ll start. First boot walks you through setting up the language, choosing a new password, connecting to wifi, and updating the OS and pre-installed software. The 400 comes with Raspberry Pi OS (formerly known as Raspbian) which, as you can probably guess from its old name, is based on Debian. The Raspberry Pi OS can be downloaded for the Pi, but can also be downloaded for desktop machines too: https://www.raspberrypi.org/downloads/. That same URL has links for other Pi compatible OSes such as Ubuntu Mate, regular Ubuntu, LibreELEC, etc. Getting everything updated took about 15 or 20 minutes. The 400 then reboots and is ready for action.
SOFTWARE Pre-installed on the 400 is: Programming: BlueJ Java IDE Geary Programmer’s Editor Greenfoot Java IDE Mathematica Mu Node-RED Scratch Scratch 2 Scratch 3 Sense HAT Emulator Sonic Pi Thonny Python IDE Wolfram Education: SmartSim

FIRST IMPRESSIONS As I said at the start of this article, I’m no Pi programmer so I’m just looking at this from the point of it being a very small form PC. My first experiment though, was to try it with my USB battery-pack to see if it could be completely portable. The answer is: yes. Running it from the USB battery pack showed it using approximately 5V and using only about 0.7A. Yes, it would briefly jump to around 1A when several things were loading, but it would happily run several pieces of software and sit around the 0.6A or 0.7A mark. So it would certainly run for a while on a decent USB pack. Although, I’m told (by Erik, so it must be true) that it should really use a 2.5A USB port for peak performance. My USB pack uses 5V/3A. So, all good there.
Just for the laughs, I hooked the 400 kit and my USB powered 13” Labists monitor to my USB battery pack. The USB battery pack is listed as 20,000mAh with two USB outputs. From a quick test (after an hour of use), I reckon I can get a good 5hrs use from this setup. I think that’s pretty impressive considering that’s a PC and a 13” monitor running off USB. A laptop might get you only 2 hours and need mains power to recharge.
CONCLUSION I’ve really only fired it up, updated it, installed a few bits and bobs, and clicked a few things here and there. But I like it. I managed to install Minetest and its associated game add-on; MineClone2. Worked great and kept me amused for several hours. I did initially forget that it was a Pi and was erroneously trying to install AMD64 .deb files. Oops! One ‘quirk’ I’ve noticed is when it’s taken offline. I’m not sure if it’s a bug or a feature, but when the 400 doesn’t have Wi-Fi, it will have the wrong date and time. I can’t find a way to manually set the date/time, only a location. Seems a bit odd that it can’t hold the date/time…
