B Full __top__ Schematic - Raspberry Pi 4 Model

Essential for designing enclosures, showing exact port placements and hole dimensions.

: The schematic reveals a dedicated high-speed bus connecting the SoC to LPDDR4-3200 SDRAM , which is available in 1GB, 2GB, 4GB, or 8GB configurations. Power Management and USB-C Raspberry Pi 4 Model B Full Schematic

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) Unlike its predecessors, this chip uses a 28nm process

A Power Management Integrated Circuit that regulates and distributes various voltage rails across the board.

With the full schematic in hand, you can start designing your own custom projects. Here are some examples:

The official schematic spans approximately 10 to 12 pages. It is dense but logically organized. Let’s open the PDF and walk through it.
