The subsequent revision (Rev 1.2) corrected this issue by properly separating the CC lines, each with its own 5.1K resistor. If you are using an original Rev 1.1 Pi 4B, the schematic provides the definitive explanation for any USB-C power problems you may encounter.

is a powerhouse of single-board computing, offering a dramatic performance increase compared to its predecessors. For engineers, makers, and electronics enthusiasts, understanding the underlying schematic of this device is key to unlocking its full potential, troubleshooting issues, and integrating it into advanced projects. This article explores the full schematic, core components, and design architecture of the Raspberry Pi 4 Model B Introduction to the Raspberry Pi 4 Schematic Raspberry Pi 4 Model B Full Schematic

The schematic illustrates the LPDDR4 SDRAM integration.

The Raspberry Pi Foundation publishes the official Raspberry Pi 4 Model B schematic PDF on its product documentation site; search “Raspberry Pi 4 Model B schematic” on Raspberry Pi’s documentation pages to download the official files.

The Raspberry Pi 4 Model B has undergone several incremental hardware revisions. Each revision changes some components or routing, but after the first release. This has led to confusion and the well‑known GitHub issue #2233 : “Raspberry Pi‑4 schematics are incomplete and stale”. Power rail for the VideoCore VI GPU and internal SoC fabric

Powers standard logic circuits, the microSD card slot, and the 40-pin GPIO header.

For the maker community, the Raspberry Pi 4 Model B represents a quantum leap in single-board computing. With its 64-bit quad-core processor, up to 8GB of LPDDR4 RAM, dual 4K display output, and true Gigabit Ethernet, it blurs the line between a hobbyist tool and a desktop replacement.

For commercial products that integrate a Raspberry Pi (e.g., an industrial controller with a Pi 4B inside), you do not need a special license to use the schematic for integration purposes, provided you are not copying the Pi’s core circuitry.
