In addition to providing an easy-to-assemble workstation that comes loaded with free software, the Pi 400 also serves as a surprisingly effective videoconferencing platform. I ordered a Pi 400 from CanaKit late last year and was eager to explore this capability. + +### Easy setup + +After unboxing my Pi 400, which came in this lovely package, the setup was quick and easy. + +![Raspberry Pi 400 box][3] + +(Don Watkins, [CC BY-SA 4.0][4]) + +The Pi 400 reminds me of the old Commodore 64. The keyboard and CPU are in one form factor. + +![Raspberry Pi 400 keyboard][5] + +(Don Watkins, [CC BY-SA 4.0][4]) + +The matching keyboard and mouse make this little unit both aesthetically and ergonomically appealing. + +Unlike earlier versions of the Raspberry Pi, there are not many parts to assemble. I connected the mouse, power supply, and micro HDMI cable to the back of the unit. + +The ports on the back of the keyboard are where things get interesting. + +![Raspberry Pi 400 ports][6] + +(Don Watkins, [CC BY-SA 4.0][4]) + +From left to right, the ports are: + + * 40-pin GPIO + * MicroSD: a microSD card is the main hard drive, and it comes with a microSD card in the slot, ready for startup + * Two micro HDMI ports + * USB-C port for power + * Two USB 3.0 ports and one USB 2.0 port for the mouse + * Gigabit Ethernet port + + + +The CPU is a Broadcom 1.8GHz 64-bit quad-core ARMv8 CPU, overclocked to make it even faster than the Raspberry Pi 4's processor. + +My unit came with 4GB RAM and a stock 16GB microSD card with Raspberry Pi OS installed and ready to boot up for the first time. + +### Evaluating the software and user experience + +The Raspberry Pi Foundation continually improves its software. Raspberry Pi OS has various wizards to make setup easier, including ones for keyboard layout, WiFi settings, and so on. + +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 (which I regularly use with my other Linux computers) to one of the USB 3.0 ports. + +The operating system recognized the Logitech webcam, but I could not get the microphone to work with [Jitsi][7]. I solved this problem by updating to the latest [Raspberry Pi OS][8] 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. I can use open source videoconferencing sites, like Jitsi, and common proprietary ones, like Google Hangouts, for video calls, but Zoom was entirely unsuccessful. + +### Learning computing with the Pi + +The icing on the cake is the Official Raspberry Pi Beginners Guide, a 245-page book introducing you to your new computer. Packed with informative tutorials, this book hearkens back to the days when technology _provided documentation_! For the curious mind, this book is a vitally important key to the Pi, which is best when it serves as a gateway to open source computing. + +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 Opensource.com's [many Raspberry Pi articles][9]. + +I paid US$ 135 for my Raspberry Pi 400 because I added an optional inline power switch and an extra 32GB microSD card. Without those additional components, the unit is US$ 100. It's a steal either way and sure to provide years of fun, fast, and educational computing. + +-------------------------------------------------------------------------------- + +via: https://opensource.com/article/21/3/raspberry-pi-400-review + +作者：[Don Watkins][a] +选题：[lujun9972][b] +译者：[译者ID](https://github.com/译者ID) +校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 + +[a]: https://opensource.com/users/don-watkins +[b]: https://github.com/lujun9972 +[1]: https://opensource.com/sites/default/files/styles/image-full-size/public/lead-images/life-raspberrypi_0.png?itok=Kczz87J2 (Raspberries with pi symbol overlay) +[2]: https://opensource.com/article/20/11/raspberry-pi-400 +[3]: https://opensource.com/sites/default/files/uploads/pi400box.jpg (Raspberry Pi 400 box) +[4]: https://creativecommons.org/licenses/by-sa/4.0/ +[5]: https://opensource.com/sites/default/files/uploads/pi400-keyboard.jpg (Raspberry Pi 400 keyboard) +[6]: https://opensource.com/sites/default/files/uploads/pi400-ports.jpg (Raspberry Pi 400 ports) +[7]: https://opensource.com/article/20/5/open-source-video-conferencing +[8]: https://www.raspberrypi.org/software/ +[9]: https://opensource.com/tags/raspberry-pi
