Full [updated] Schematic — Raspberry Pi 4 Model B

Includes dual-band 2.4/5.0 GHz wireless LAN and Bluetooth 5.0. 4. Power Management and PoE

Q: What can I do with the Raspberry Pi 4 Model B full schematic? A: You can use the schematic to design custom PCBs, expand the GPIO, optimize power consumption, and more. Raspberry Pi 4 Model B Full Schematic

The Raspberry Pi 4 Model B is a remarkable piece of engineering, and the available documentation—imperfect though it may be—provides enough transparency to enable a vast ecosystem of hardware innovation. Whether you are a seasoned embedded engineer or a curious maker, the schematic is your first step toward truly understanding what makes the Pi 4 tick. Includes dual-band 2

The PMIC ensures that the board remains stable under heavy loads, which is why a 3A power supply is strictly recommended. Raspberry Pi 3. High-Speed Connectivity and I/O A: You can use the schematic to design

The official "reduced" schematic does not differentiate between these revisions. There is no published schematic for v1.2 or v1.4, and the user community has noted that updated schematics would be beneficial. If your Pi 4 has a revision beyond the initial release, use the official schematic as a general reference but be aware that minor component values and placements may have changed.

is a highly versatile single-board computer (SBC), but engineers and developers often encounter a major challenge: . To protect intellectual property, Raspberry Pi Ltd. releases only a Reduced Schematic via the Raspberry Pi Product Information Portal . This official document covers consumer-facing I/O interfaces, power delivery blocks, and basic pinout mapping, but excludes the core proprietary board traces, full Bill of Materials (BOM), and internal System-on-Chip (SoC) logic paths.
