The 5 Best Raspberry Pi 400 Projects to Start Today


Performance overall was good, with aGeekbench 5single-core score of 212 and a multi core score of 642. That’s a nice boost over the 8GB Pi 4 we tested , even with only 4GB of RAM. There’s a BCM2711 SoC with four Arm Cortex-A72 cores and a VideoCore VI graphics processor, 4GB of LPDDR4 memory — both the minimum and the maximum, with no sign of a 2GB or 8GB model at launch — and a microSD slot for storage. The Raspberry Pi 400 has a quad core 1.8GHz processor, with 4GB of RAM, in a keyboard formfactor.

Cat6 Ethernet Patch Cable – Snagless RJ45, Stranded, 550Mhz, UTP, Pure Bare Copper Wire, 24AWG, 7ft, Black Save the time and hassle of building Ethernet cables by using these fixed-length UTP Cat6… You can then install 1 OS per SD card and because the SD card is easily accessible you just shut down change the card and put a different operating system. And after you become enchanted with Linux and all that it offers by using the Pi, you’ll have months of exploration ahead, thanks to’s many Raspberry Pi articles.

Designed to be an “object of desire,” the Raspberry Pi Foundation’s new device is a marked departure from the norm — and faster than a Pi 4. Once the dd operation is complete, boot up the Raspberry Pi 400 with the microSD card plugged in. This process can take a while, depending on your PC, your microSD card’s speed, and the size of the Kali Linux image. Use the dd utility to image this file to your microSD card (same process as making a Kali USB. Synthesizers used to be bulky and expensive, but that has changed with the increase in the popularity of software synths. Luckily, this Adafruit tutorial shows how you can make your own synthesizer with a Raspberry Pi 400 by using a Cyberdeck HAT, an ADC + DAC (analog-to-digital/digital-to-analog) breakout board, and a PiTFT touchscreen.

At the rear of the Raspberry Pi 400 are all of the ports, the largest of which is a 40-pin header for the GPIO. Moving along, we find a microSD card slot , two micro HDMI ports offering 4K output, two USB 3.0 ports and a single USB 2.0 port with a Gigabit Ethernet port rounding off the port selection. Plugging a keyboard into a TV and launching a code editor to build your first app remains exciting, and by offering complete kits for £93.90, or $110.41 (a standalone Pi 400 is only £66.90, or $78.66), it’s an affordable way to get started with computing. Educational bundles are available, too, so schools can quickly set up networked computer labs with low-cost devices and basic monitors, ready to get whole classes online and coding. We used Raspberry Pi OS for our test system, installing it on a Crucial BX GB 2.5-inch SSD, connected via a SATA-to-USB 3.0 adapter, using its Wi-Fi to connect to our test network. Yes, it’s a bit ungainly, having USB-connected storage like this, but it’s fast enough for most purposes and provides a lot more space than an 8GB or 16GB MicroSD card.

Orange Pi has presented the Orange Pi 800, its version of the Raspberry Pi 400. The Orange Pi 800 comes with a Rockchip RK3399 SoC, 4 GB of RAM, 64 GB of storage and a 6-row keyboard, among other features.

That said, it’s important to remember that the entire kit retails for $100. Within the limits of the Pi 400’s very generous price, it’s not really fair to complain too hard about a few aesthetic gaffes here and there! Consumers with a few extra dollars to spend might want to consider replacing the Pi 400’s mouse with something a bit more functional, though… And a full-sized keyboard might not be a bad idea while you’re at it.

“We’ve been doing bits of outreach to help kids who’ve been sent home from school with no computer,” Upton explains. “This is a program called Pi Drop, that the Foundation is running.” “It’s a nod to a pretty common naming convention, the sort of three digit number that ends in zero,” Raspberry Pi Foundation founder Eben Upton tells us in an interview. The wireless chip on the Raspberry Pi 400 is NOT supported by nexmon, so if you are planning on doing wireless attacks or research, you will need to use an external wireless device. We recommend using the 32-bit image on Raspberry Pi devices as that gets far more testing, and a lot of documentation out there expects you to be running RaspberryPi OS which is 32-bit.

Is The Raspberry Pi 400 Really A ‘Complete’ Personal Computer?

While you may well be able to adapt many existing projects for Raspberry Pi, the project ideas listed below are easy DIY builds you can start today and make use of the Raspberry Pi 400’s form factor. The latest Raspberry Pi bundles the microcomputer inside a keyboard for ease of use, portability, and performance. The Raspberry Pi 400 promises to be a boon to the homeschool market.

Late Friday afternoon, I got an exciting SMS notification—my review sample of the new Raspberry Pi 400 had arrived. I learned of the new Pi model last week while interviewing Raspberry Pi founder Eben Upton and Canonical Desktop Engineering Director Software development Martin Wimpress about Ubuntu 20.10’s newly improved desktop support for the Pi hardware family. A departure from the norm, the Raspberry Pi 400 is a great all rounder. We get the same Raspberry Pi experience, but with far fewer wires and setup.

The Performance

The Raspberry Pi 400 has a relatively small but effective keyboard that you can fit into your productivity workflow. LibreOffice comes preloaded in Raspberry Pi OS and includes applications such as LibreOffice Base, Writer, Calc, Draw, and Impress. With this software suite, you can perform word processing, note-taking, spreadsheet manipulation, database management, presentations, and so on.

I began testing the Pi 400 using its native Raspberry Pi OS Linux distribution—which is basically Debian with LXDE and a lot of middleware optimizing it for the Pi. Unfortunately, there’s almost nothing in the way of standard benchmarking utilities that run on ARM Linux—all I could find was the Phoronix Test Suite, which would have required more time to run than I had to test the device in total. So for the most part, I’m going to talk about my subjective experience, rather than hard numbers. Finally, there’s no 3.5mm audio jack on the Pi—if you’ve got it hooked to a television or a monitor with speakers, it can deliver audio over HDMI; otherwise you’ll need a supported USB audio device. I tested with an inexpensive USB gaming headset, which worked fine.

The single-board Raspberry Pi devices have gone a long way to delivering on that promise, via kits that bundle keyboard and mouse for a full computing experience. ZDNET’s recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings Six Rules of Thumb for Scaling Software Architectures by Ian Gorton as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing. The GPIO pins remain accessible, so if you want to explore beyond the desktop, you can connect components and prototype your projects.

The operating system recognized the Logitech webcam, but I could not get the microphone to work with Jitsi. I solved this problem by updating to the latest Raspberry Pi OS release with Linux Kernel version 5.4. This OS version includes many important features that I love, like an updated Chromium browser and Pulse Audio, which solved my webcam audio woes. Command Line Commands CLI Tutorial I can use open source videoconferencing sites, like Jitsi, and common proprietary ones, like Google Hangouts, for video calls, but Zoom was entirely unsuccessful. The software included on the microSD card was the August 2020 Raspberry Pi OS release. After initial startup and setup, I connected a Logitech C270 webcam to one of the USB 3.0 ports.

The Raspberry Pi 400 is the keyboard computer counterpart to the Raspberry Pi 4. It has a custom-built Raspberry Pi board built into a keyboard form factor. Interesting specs include a Broadcom BCM2711 quad-core processor, 4GB of RAM, two micro HDMI ports, dual-band wireless connectivity, Gigabit Ethernet, and Bluetooth.

The Raspberry Pi 400 is ideal for building your own synthesizer because it has enough processing power to handle all the data you need to process in order to emulate an analog synthesizer. This project requires some wiring and coding knowledge, but the steps are detailed enough to follow. Once your Raspberry Pi synthesizer is complete, it’s time to make your own synth-pop music.

Raspberry Pi 400 Review: Faster CPU, New Layout, Better Thermals

Standalone units retail for $70 which is $15 more than a Raspberry Pi 4, but we get an added keyboard and a great CPU speed bump. The range of Raspberry Pi cameras are cheap and effective add-ons that provide a fun stream of projects. If you want to create camera projects, then the Raspberry Pi 400 is not for you. The Raspberry Pi Model B has seen the same board layout since the Raspberry Pi B+ arrived in 2014. Sure the Raspberry Pi 4 swapped the Ethernet and USB ports around, but the same basic design has persisted.

SparkFun Qwiic pHAT Extension for the Raspberry Pi 400 provides you with a quick and easy solution to access all of the 400’s GPIO, stack your favorite HAT right-side up, or connect a Qwiic-enabled device to the I2C bus (GND, 3.3V, SDA, and SCL). “There was also a little bit of a thought about corporate, actually,” Upton adds. Docking stations and cyberdecks are not the only projects for a Raspberry Pi 400. If you’re down for it, you can turn your keyboard computer into a low-budget gaming device. It won’t be running Far Cry or Call of Duty any time soon, but you can emulate old, less-demanding games on it.
