At the center of the schematic sits the Broadcom BCM2711 SoC. Unlike its predecessors, this chip uses a 28nm process. It features a quad-core Cortex-A72 architecture. This shift allows for faster clock speeds and better thermal efficiency. Quad-core 64-bit ARM v8. Speed: 1.5GHz (upgradable via firmware). Video: VideoCore VI supports OpenGL ES 3.x. Power Delivery and Management (PMIC)
The schematic shows two micro-HDMI ports. These are driven by the SoC's upgraded display pipeline. It supports two 4K displays simultaneously at 30Hz, or a single 4K display at 60Hz. 2x Micro-HDMI. Audio: Digital audio is embedded in the HDMI signal. Raspberry Pi 4 Model B Full Schematic
: The Pi 4 lacks the polyfuse found on older models, meaning users must ensure their power supply does not exceed the recommended 5.25V. High-Speed I/O and Connectivity At the center of the schematic sits the Broadcom BCM2711 SoC
Are you designing a custom hat, hacking your hardware, or just dying to know how the Broadcom BCM2711 talks to the USB 3.0 controller? While the full, "no-secrets" BOM (Bill of Materials) is rarely released for Raspberry Pi flagship boards, the official Reduced Schematics This shift allows for faster clock speeds and
If you are designing a custom PCB or carrier board, look into the Compute Module 4 (CM4) documentation. It is "loosely based" on the Pi 4 Model B
