      Raspberry Pi 400 Launched

      4
      By Matt on November 2, 2020 Pi Models

      The Raspberry Pi 400 is the latest product to be released by the Raspberry Pi Foundation. The 400 is a compact keyboard with a custom Pi 4 PCB inside. This gives you a compact quad-core computer with all the connectors on the rear edge. Plug in a monitor, mouse and power cable and you have a desktop computer with GPIO pins.

      Raspberry Pi 400 with Mouse

      The device I got to play with was supplied in a plain white carton, with a mouse, USB-C power supply, microSD card, HDMI cable and a copy of “The Official Raspberry Pi Beginner’s Guide” book. I expect the retail version will include printed “retail” packaging.

      I used the new Pi to create this blog post and it worked out quite nicely.

      Raspberry Pi 400 Specifications

      The physical specifications are:

      • Weight : 386g
      • Length : 285mm
      • Depth : 122mm
      • Height : 22mm
      • Power Input : 5V USB-C

      Given the Pi 400 is based on a Pi 4 the specifications are similar :

      • Broadcom BCM2711 1.8GHz quad-core 64-bit ARM Cortex-A72 CPU
      • VideoCore VI graphics, supporting OpenGL ES 3.x
      • 4Kp60 hardware decode of H.265 (HEVC) video
      • 1080p60 hardware decode of H.264 (AVC) video
      • 1080p30 hardware encode of H.264 (AVC) video
      • Dual HDMI interfaces, at resolutions up to 4K
      • Single-lane PCI Express 2.0 interface
      • 2.4GHz and 5GHz IEEE 802.11b/g/n/ac wireless LAN and Bluetooth 5.0
      • Gigabit Ethernet PHY with IEEE 1588 support
      • 28 GPIO pins, with up to 6 × UART, 6 × I2C and 5 × SPI

      Processor

      The processor is the same Broadcom BCM2711 as used in the Pi 4 but it has been clocked at 1.8GHz rather than the standard 1.5GHz. This has been possible thanks to a large heatsink that is almost the same size as the keyboard itself.

      Memory

      The model I got to test was fitted with :

      • 4GB LPDDR4-3200 SDRAM

      This appears to be the only configuration available but if there was demand I suspect an 8GB version would be possible.

      The Keyboard

      The keyboard itself is a matrix style and feels very similar to a keyboard you would find on a laptop.

      Raspberry Pi 400

      Its features include :

      • 79-keys (78-keys US version)
      • Num Lock, Scroll Lock, and Caps Lock LEDs
      • Pi logo key
      • Power on/off key

      It looks almost identical to the conventional official Pi keyboard and almost certainly shares some design history.

      Rear Connectors

      The headline feature of the 400 is that all the connectors are available on the rear edge. This makes for a neater desktop setup without the Pi being dragged off your desk by the HDMI cable.

      Pi 400 Rear Connectors

      Looking the the rear of the device from left to right the connectors are :

      • 40 pin-GPIO Header
      • microSD card slot
      • 2x micro HDMI
      • USB-C power
      • 2x USB 3.0
      • 1x USB 2.0
      • Gigabit Ethernet

      On the far-right is a Kensington security slot (K-slot) which provides a simple way to secure the device and prevent anyone walking away with it. This will be of interest to anyone wanting to use the 400 in a classroom or public space.

      Pi 400 Gigabit Ethernet

      Due to the form factor there are number of Pi features that are missing from the Pi 400. These include the DSI, CSI and 3.5mm sockets. Audio can be routed via the HDMI connector if your monitor has integrated speakers. The lack of camera interface is perhaps frustrating but really this iteration of the Pi isn’t designed for camera based projects.

      I’m sure someone will pop-open the plastic shell and we will see what hardware is available inside. UPPDATE : The PiHut opened theirs up so you don’t need to!

      Pricing

      The base unit is available for £67 with the starter kit selling for £94.

      Videos

      Here are two videos I created to show the 400 in more detail. The first one is two minutes long …

      And a slightly longer version …

      Final Thoughts

      The Raspberry Pi 400 is a welcome addition to the Raspberry Pi line-up. It is a great start for beginners while also providing a neat desktop solution for everyone else.

      The physical design makes it more suitable for permanent use on a desk. A conventional Pi board may be better suited for many other projects especially if they need a CSI based camera.

      Buy a Raspberry Pi 400

      The Raspberry Pi 400 will be available from many of the places you have previously purchased Pi products from. In the UK this will include :

      • The PiHut
      • Farnell/CPC
      • PiMoRoni

      Please search for Approved Resellers in your region on the Official Pi website.

      The Official website states that “Raspberry Pi 400 unit will remain in production until at least January 2026”.

      Disclaimer : I was sent this device and accessories free of charge. This came with no restrictions or expectations other than to not mention it until the official launch. All comments made in this blog post and my supporting videos are my own honest opinions based entirely on what I found in the box.

        The first Raspberry product that reminds me of the great homecomputers!

        Plus points compared to the Pi 4:

        – a real computer instead of a PCB!
        – the package sells for less than a Pi 4 with accessories
        – very well thermal control, no heat problems
        – newer SOC means lower temperature and allows higher clock speed 1.8GHz (1.5 for the Pi 4)
        – nice compact and PCB safe case

        Minus points:
        – no camera connector (use an USB Cam!)
        – no display connector
        – no composite video
        – no analog audio (a pity for people with a cheap HDMI/DVI monitor without audio)
        – GPIO connector not that easy to access (use an extender cable)
        – one USB 2 port less

        A great computer!

        According to the Pihut teardown, this IS a compute module, it does not “contain” one.

          It is a completely custom Pi board. So yes it does not contain a Compute module.

        An HDMI audio extractor works fine. Between $20 and $70 Canadian, stereo 3.5mm jack and SPDIF optical 5.1 channel digital output.
