The Raspberry Pi 4 announcement comes directly from the Raspberry Pi Foundation: the new card is already available for purchase, offered in three versions that differ in the amount of RAM on board. In any case the computing power increases up to three times, to support more complex operations.
Raspberry Pi 4: the specifications
Let’s start by taking a look at the technical specifications sheet: there is a Broadcom BCM2711 quad core 1.50 GHz processor (ARM Cortex-A72 64-bit), VideoCore VI graphics chip with OpenGL ES 3.x support, RAM memory 1, 2 or 4 GB (LPDDR4-2400), Gigabit Ethernet port, dual band 802.11ac WiFi module, Bluetooth 5.0, two USB 2.0 ports, as many USB 3.0, microSD slot for loading operating system and data, GPIO connector ( General-Purpose Input / Output) with 40 pins and two micro-HDMI video outputs with 4K resolution up to 60 fps.
Raspberry Pi 4: versions and price
As written above, there are three versions of Raspberry Pi 4, differentiated by the amount of RAM on board. Here are the prices for the US market.
Raspberry Pi 4 (1 GB): $ 35.00;
Raspberry Pi 4 (2 GB): $ 45.00;
Raspberry Pi 4 (4 GB): $ 55.00.
A question that could be asked by the less savvy users is: what is it for? The only limits are those dictated by imagination and creativity (as well as by resources, however not comparable with those of a PC). There are those who use a Raspberry Pi as a device for the management of multimedia content, those who transform it into a retrogaming machine, others still in a hub for smart home control. On the Net there are tutorials and projects of all kinds, each of them based on the use of a different software to load on the card.
