Raspberry Pi Official Magazine #134

There's only one thing everybody is talking about this month – the announcement of Raspberry Pi 5. Raspberry Pi's upcoming small-factor computer is a giant leap forward in speed and features. Managing to fit so many new components onto the same-sized board is an incredible feat of engineering. Raspberry Pi 5 is up to three times as fast as the – already speedy – Raspberry Pi 4 it replaces; Raspberry Pi 5 is a full desktop-class computer. It has dual-camera and display support; Raspberry Pi connector for PCIe with an M.2 drive HAT on the way. It even features a power button (hurrah!) and a real-time clock. And it still has the GPIO pins for homemade hacking and making. It's perfect! There's a lot packed in Raspberry Pi 5, so…

Raspberry Pi 5. Those are all the words you need to hear this month. This is the moment we've been waiting for. The next generation of Raspberry Pi has been in development for years, and we can finally lift the wraps on the full specifications, design process and features on the new board. For the first time, this computer features silicon designed in-house by Raspberry Pi. The new chip RP1 allows Raspberry Pi 5 to deliver a huge improvement in peripheral performance and functionality. It's also opened up a lot of space on the board, which now features 10 new components on the classic form factor. Raspberry Pi 5 is still the single-board computer we know and love, but at its heart sits a 2.4GHz quad-core Arm Cortex-A76 CPU that…

RAM Here we have 8GB of LPDDR4 in the form of a Micron chip PCIe A new PCI Express high-speed expansion bus is positioned on the edge of the board. An upcoming adaptor will enable an M.2 drive to be connected directly to Raspberry Pi 5, along with other custom devices. Power The Renesas/Dialog DA9091 “Gilmour” power management chip is custom silicon that provides power supplied to the various components Power Button A power button, one of the most heavily requested features, has finally been added to Raspberry Pi 5. The status LED sits adjacent USB-C power Raspberry Pi 5 is powered by an external USB-C power supply BCM2712 chip The silver heart of Raspberry Pi 5 is the new Broadcom BCM2712 SoC (System-on-chip) architecture. It contains an ARM Cortex-A76…

Battery Raspberry Pi 5 has a tw o-pin JST (Japan Solderless Terminal) port marked BAT. This is used to connect a battery (or other power source) to the new Real Time Clock (RTC). Raspberry Pi RP1 Raspberry Pi has been developing RP1 for a long time. RP1 is a new communications chip. RP1 is custom silicon designed by Raspberry Pi that connects the CPU to the ‘slower’ components on the board (of course, these slow components can still function incredibly quickly). In the case of Raspberry Pi 5, RP1 controls the input and output (I/O) for the GPIO pins, USB ports, CSI/DSI ports and Ethernet. It is connected to the BCM2712 SoC via a 4-lane PCI-express bus. The GPIO pins have the same function and layout as before, so most…

Raspberry Pi Case Alongside Raspberry Pi 5 comes a new case with powerful new features. It retains the white and red modular scheme of the original case, and now contains four separate compartments. There is the red base, which Raspberry Pi 5 sits on, with a white frame in the middle. New to this case is a clear shelf with a fan on board (that connects to the fan socket next to the Ethernet port). This shelf has a cutout section enabling access to the GPIO pins, and a final lid, with airflow spacing, covers everything into a neat package. Inside the box you will also find a heatsink to attach to Raspberry Pi 5's main processor and four stickon rubber feet. Active Cooler An alternative cooling solution is also…

BIO CTO (HARDWARE) James has been at Raspberry Pi for over ten years. You'll find his signature on a Raspberry Pi 5 under the USB ports. What is a southbridge? The southbridge in a traditional legacy PC is the chip that handles most of the medium-speed input/output (I/O) functions, such as USB, storage, networking, etc. In comparison, the northbridge provides the highest-speed interfaces: to SDRAM and PCI Express. It's been over four years since Raspberry Pi 4 was released, but parts of Raspberry Pi 5 have been in development for far longer. We sat down with James Adams, CTO (Hardware) at Raspberry Pi, to talk about the new technologies on the board and what they bring to Raspberry Pi. RP1 – an in-house southbridge Raspberry Pi 5 is coming out…
