The Raspberry Pi Foundation has launched a new single-board: Raspberry Pi 4 has the same price as the 2012 Raspberry Pi Model B, but with completely updated hardware compared to the Raspberry Pi 3 released three years ago. Suffice it to say that it can manage up to two 4K screens at 30Hz or only one 4K display at 60Hz with H.265 video decoding support.
On board we find a Broadcom BCM2711 quad-core processor at 1.5GHz (Cortex-A72) with VideoCore 6 GPU, much more powerful than previous models, 1GB to 4GB RAM depending on the models and microSD card slot for storage. Connectivity has also improved and now includes two USB 3.0 ports, two USB 2.0 ports, a USB Type-C port for charging, 3.5 mm audio jacks and two micro HDMI 2.0 ports, plus Gigabit Ethernet, WiFi 802.11ac and Bluetooth 5.0. Do not miss the 40-pin connector to add compatible modules and then expand the functionality of the card.
Raspberry Pi 4 Model B
Raspberry Pi 4 Model B is already available on the market in three different configurations: base with 1GB of RAM at $ 35, intermediate with 2GB of RAM at $ 45 and top-of-range with 4GB of RAM at $ 55. Please note that to be able to turn on the board you will need to purchase at least one microSD card for storage, a power supply and various peripherals. For 120 dollars, the Raspberry Pi Foundation offers the Raspberry Pi 4 Desktop Computer kit with a 4GB Raspberry Pi 4 Model B, a keyboard, a mouse, a power supply, a case, two micro HDMI-HDMI cables and a 16GB microSD card, with preloaded software with a user guide.
Thanks to the support of USB 3.0, the speed of Gigabit Ethernet will be a little faster than that recorded in the Raspberry Pi 3, which can reach up to 300 Mbps with the computer’s USB 2.0 bridge. Important upgrade from Bluetooth 4.2 to Bluetooth 5.0, as well as the migration from a 1.4GHz ARM Cortex-A53 to a 1.5GHz ARM Cortex-A72 with a new GPU and two micro HDMI (instead of one full-size) .
This last feature will make it easier to connect more displays but – considering that the new Raspberry Pi has the same dimensions as its predecessors – the positioning of the ports (including USB and Ethernet) has been changed, so the new single-board does not will be compatible with the 85.6 x 56.5 mm cases of the previous models. In fact, Raspberry Pi Foundation presented a new $ 5 frame but other third-party and / or DIY versions will soon arrive. HATs and all accessories that use the 40-pin expansion header should work without problems.
Raspberry Pi 4 Model B
There are other dev-boards that can stand up to Raspberry Pi, especially in benchmarks, but the advantage of Raspberry Foundation devices is the large community of developers and users, which makes it easy to find resources and support for these small computers. And according to what was declared in the launch phase, the official support for the Raspberry Pi 4 will be assured at least until January 2026.
