Raspberry Pi 4

The Raspberry Pi 4 is the fourth generation of the Raspberry Pi flagship series of single-board computers. Developed by Raspberry Pi Holdings and released on 24 June 2019, it introduced significant upgrades over its predecessor. At its core, the Pi 4 features a Broadcom BCM2711 system on a chip (SoC), which has a quad-core 64-bit ARM Cortex-A72 CPU and a VideoCore VI GPU, offering a boost in processing and graphics performance. Among other notable hardware improvements are the addition of two USB 3.0 ports, the inclusion of true gigabit Ethernet, and support for dual displays at 4K resolution through two micro-HDMI ports. Furthermore, RAM options go beyond the 1 GB standard of previous models, adding 2, 4, and 8 GB variants. While the base model with 1 GB of RAM maintained the $35 price point that had become a hallmark of the Raspberry Pi series, the higher RAM variants exceeded this price due to increased production costs. On 28 September 2023, the Raspberry Pi 5 was announced, succeeding the Raspberry Pi 4.
