Raspberry Pi 4 is available for sale with prices starting below 40 euros.

This is an update, the manufacturer explained, that touches almost all the elements of the platform and that for the first time provides a level of performance similar to that of a PC, at least for most users, while maintaining the interface capabilities and hackability of the

The following are the main technical features of Raspberry Pi 4 Model B, the new generation of single-board computers used not only for training projects, but also for the development and prototyping of solutions in a wide range of areas: sm

Cortex-A72 ARM 64-bit 1.5 GHz quad-core CPU (for performance that the manufacturer indicates about three times higher).

A 64-bit 1.5 GHz quad-core (for performance that the manufacturer indicates about three times higher). 1 GB, 2 GB or 4 GB of SDRAM LPDDR4, depending on the model.

Gigabit Ethernet full-throughput.

Full-throughput. Wireless network connectivity 802.11ac dual-band.

. Bluetooth 5.0 support.

. Two USB 3.0 ports and two USB 2.0 ports.

and two USB 2.0 ports. Support for double monitor, with resolutions up to 4K.

, with resolutions up to 4K. VideoCore VI graphics, with OpenGL ES support 3.x.

, with support. 4Kp60 hardware decoding of NEVC videos.

video NEVC. Complete compatibility with previous products Raspberry Pi.

For the first time, the single-board computer is offered with three memory options, 1 GB, 2 GB and 4 GB, with prices naturally growing.

As a power connector, the new version switches from the micro-B USB to the USB-C, which, explained the manufacturer, supports 500mA more power, ensuring the complete availability of 1.2A for USB downstream devices, even in case of

Raspberry Pi 4 Model BIn addition, to allow dual output for display within the footprint of the existing card, the Raspberry Pi Foundation has chosen to replace the HDMI type-A (full-size) connector with a pair of connectors

The Gigabit Ethernet connector was moved to the top right on the board, from the previous position at the bottom right, greatly simplifying the PCB routing. The 4 pin PoE (Power-over-Ethernet) connector remains in the same position, so Raspberry Pi 4 remains compatible with the HAT PoE.

The Ethernet controller on the main SoC is connected to an external PHY Broadcom via a dedicated RGMII connection, providing a full throughput. The USB comes with an external VLI controller, connected via PCI Express Gen 2 single lane: it provides a total of 4 Gbps of bandwidth, shared between the four ports.

All three connectors on the right side of the board protrude from the edge of an additional millimeter, with the aim of simplifying the design of the case. In all other respects, the connector and layout of the mounting holes remain the same, to ensure compatibility with the HAT (Hardware Attacked on Top, board add-ons for Raspberry Pi) and other existing accessories

The software is also updated. To support Raspberry Pi 4, the manufacturer is distributing a radically renovated operating system, based on the upcoming Debian 10 Buster release. This means that many technical improvements are introduced, behind the scenes, along with a modernised user interface and updated applications, including the Chromium 74 web browser.

Changes to connectors and shape factor bring with them the need for new accessories. Raspberry Pi has worked with various partners in the development of new homes, power supplies, HDMI cables and other accessories.
