The Raspberry Pi 400 is a minicomputer integrated with a keyboard. The device’s appearance is reminiscent of the iconic Commodore 64. What is worth knowing about it?
Raspberry Pi 400 - high power and full computer functionality
The Raspberry Pi minicomputer integrated with a keyboard appeared on the market in 2020 in November. The devices are based on Raspberry Pi 4B in a configuration with 4GB of RAM. The hardware is built into the original keyboard in the US layout. The Raspberry Pi’s fully functional red and white keyboard features a distinctive raspberry symbol key located between the Fn and Alt keys. Even at first glance you can recognize the similarities to the Commodore 64.
Raspberry Pi 400 is the foundation’s first project that combines a single-board computer with a keyboard equipped with communication connectors. With them, you can connect all sorts of devices and accessories to the raspberry.
Raspberry Pi 400 communication ports
All communication ports Raspberry Pi 400 are located at the rear of the case. Such a solution ensures good organization, and thus comfortable use of the device, even when all ports are used. The first is the 100/1000 Mbps Ethernet, which allows a wired connection to the Internet. This port is particularly important for users and applications that require a stable network connection. Another port is USB Type A in the 2.0 standard. It is easily recognized by the white element. The port is designed for connecting various computer accessories (such as a mouse).
The next two ports are also USB Type A, but this time we are dealing with the 3.0 standard. Interfaces of this type are distinguished by fast data transmission, such as from compatible external drives. The next port, USB Type C, is used to power the device with 5 V and a maximum current of 3 A. In addition, the Raspberry Pi 400 can be powered via a GPIO socket (2×20 pins, 2.54 mm raster) with 5 V.
Other Raspberry Pi 400 communication ports
The single-board minicomputer integrated into the keyboard is also equipped with two microHDMI connectors. Ports of this type allow audio and video transmission at a maximum resolution of 4K and 60 frames per second. The Raspberry Pi 400 is equipped with a powerful VideoCore VI graphics processor allowing support for HEVC / H.265 codec, OpenGL ES3.1 and Vulcan graphics. There is also a microSD memory card slot on the back. The memory card is designed to install the operating system.
The aforementioned GPIO socket has 40 input and output pins characterized by general purpose. The socket allows the use of the following communication interfaces: UART, SPI and 12C. They can be used to connect various accessories, including sensors, LEDs and buttons.
Wireless communication
Raspberry Pi 400 also allows for wireless communication. The first option is dual-band WiFi communication at 2.4 GHz or 5 GHz 802.11./g/n/ac. The built-in WiFi module is distinguished by its full compatibility with Raspberry Pi operating system drivers. The second option for wireless connectivity is a low-power Bluetooth 5.0 module that guarantees a stable connection.
Technical specifications of Raspberry Pi 400
The heart of Raspberry Pi 400 is 4th generation single board computer in a variant with 4 GB of RAM (LPDDR4-3200 DRAM). The Raspberry is powered by a 64-bit Broadcom BCM2711 processor accelerating to 1.8 GHz. The chip’s core, on the other hand, is the proven Quad-Core ARM Cortex-A72.
Information about the keyboard
Single board minicomputer Raspberry Pi 4B is integrated with a fully functional keyboard. All keys are distinguished by their short stroke and comfortable use, making them ideal for, among other things. for data entry. The all-in-one chassis with communication connectors is great for office work as well as virtual gaming and movie watching (by connecting a monitor to one of the microHDMI ports).
Raspberry Pi 400 bundled with official accessories
The Raspberry Pi 400 comes in two variants. The first is the computer itself integrated with the keyboard. The second option, on the other hand, is set, which consists of additional accessories in addition to the main device. Choosing the second option, the user gets, among other things – optical, wired computer mouse. This official Raspberry Pi accessory comes with three physical buttons and a red colored roller.
In addition, the set includes original power supply providing stable voltage at 5.1 V. In turn, the current capacity of 3 A guarantees proper operation of the device, even under maximum load.
What else can be found in the kit? Original cable with microHDMI and HDMI connector with a length of 1 m used to connect a monitor to the Raspberry Pi 400.
In addition, the set includes memory card in microSD class 10 format with a capacity of 16 GB. The Raspberry Pi OS is installed on the memory stick. The last item in the kit is an illustrated instruction manual for the device. The manual is written in a simple and accessible manner, so even novice users should have no problem understanding it.
Additional information about Raspberry Pi 400
The compact size, combined with low weight, makes the Raspberry Pi 400 along with the monitor is perfect for work or entertainment outside the home. The use of a Kensington lock connector makes it quick and easy to attach a heavy-duty MicroSaver cable for effective theft protection. The single-board computer integrated with a keyboard is designed, among other things. For users who require fast and convenient data entry. It is perfect for programming, writing content, creating tables, charts and browsing the Internet.
