The reason is that above a certain scale, it generally makes more sense to go with a custom PCB rather than a module with a carrier board. Some folks have asked us why we did not fit the Raspberry Pi Compute Module inside. In fact, there is enough thermal margin to overclock it, if you’re so inclined. Raspberry Pi 400 contains a heat spreader that dissipates the heat across the whole unit, front and back, so that no part of it will feel too hot to touch. Raspberry Pi 400 has the same circuit layout of the power management, processor, and memory as Raspberry Pi 4, but with one major difference: we’ve adjusted the operating point to 1.8GHz! And did I mention cooling? We’ve solved the cooling challenge so users don’t have to give this any thought. The HAT functionality works better with an extender cable, which you can buy from numerous websites. We kept the GPIO connector since it is loved so much by beginners and experts alike, and this is after all a Raspberry Pi – we want people to be able to use it for tinkering and prototyping. However, the kit does come with a micro HDMI-to-HDMI cable to cheer you all up. It would have been lovely to have had full-size HDMI connectors, but in order to achieve this we would have to remove other functions, or make a bulkier unit. Like Raspberry Pi 4, it has dual micro HDMI output which achieves up to 4K video.

Raspberry Pi 400 has dual-band 802.11b/g/n/ac wireless LAN and Bluetooth 5.0. Left-handed folks and Bluetooth mouse-owners will be happy at least! Micro HDMI We have already seen a few comments about the USB ports being on the left side of the unit, and the fact that this makes the mouse cable cross over for most right-handed users. The PCB shape had to be defined early on so that the industrial designers could get on with the housing design, and I then stared endlessly at the PCB layout, trying to get one of the USB ports to route to the right side without wrecking the signal integrity of the memory or the HDMI I could not find a way to do this. It has the same USB and Ethernet system as the Raspberry Pi 4, but one of the USB2.0 ports is dedicated to the keyboard. The board inside the housing is essentially a Raspberry Pi 4 unit, but with a fresh PCB design. So, instead, we started work on the Raspberry Pi 4-based version as soon as the design for that was finalised. We had first planned to make a Raspberry Pi 3-based version, but it was clear that getting such a complex item into product wouldn’t happen until after we’d launched Raspberry Pi 4, and this would make the new product seem like a runner-up. The keyboard and mouse were the big things we needed to sort out: once the quality control and supply chain were in place for those, we could move to fitting keyboard matrices to Raspberry Pi 400s, and achieve final assembly in Sony’s manufacturing facility in Wales. Then others did the same with a Raspberry Pi Zero, and by that point we kind of expected that. Our jaws dropped – we were impressed but we couldn’t say a word. How hard could it be? Then, within a day of our announcing our new keyboard and mouse, we saw a blog from someone who had milled out the keyboard and integrated a Raspberry Pi 3 Model A+ into it. The challenge was that we needed a mouse and a keyboard: if we could manufacture a mouse and a keyboard, we could make a complete kit. Initially, the plan was for a kit with all the parts needed for people simply to open the box and get started by connecting the accessories to a “classic” credit-card sized Raspberry Pi. It’s been over four years since the original idea of a Raspberry Pi inside a keyboard was discussed, before I even started working at Raspberry Pi Towers. It’s been a journey, but it’s finally here, and I can talk about the secret Raspberry Pi 400 project! I’ll also try to cover some of the questions you asked following Eben’s announcement of Raspberry Pi 400 yesterday.
