Raspberry Pi 4 Model B Full High Quality Schematic

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.

Practical notes:

Broadcom BCM2711, Quad-core Cortex-A72 (ARM v8) 64-bit SoC @ 1.8GHz 1GB, 2GB, 4GB, or 8GB LPDDR4-3200 SDRAM Wireless 2.4 GHz and 5.0 GHz IEEE 802.11ac, Bluetooth 5.0 Ethernet True Gigabit Ethernet USB 2 × USB 3.0 ports; 2 × USB 2.0 ports Power 5V/3A via USB-C or GPIO Source: Raspberry Pi Foundation

Understanding the Raspberry Pi 4 Model B schematic bridges the gap between basic coding and advanced hardware engineering, allowing you to design more stable systems and custom peripherals with complete hardware confidence. Raspberry Pi 4 Model B Full Schematic

For users of electronic design automation (EDA) software, the schematic can be re‑created or imported:

A: You cannot replicate the Pi 4B itself, but you can design a carrier board that accepts a Compute Module 4. For the CM4, the documentation is much more extensive, including full schematics of the IO board.

While the Pi 4 boots at 3.3V signaling for legacy compatibility, the schematic supports UHS-I mode voltage switching (dropping signaling down to 1.8V) to enable much faster read/write speeds on compatible high-speed MicroSD cards. 6. The 40-Pin GPIO Expansion Header The Raspberry Pi Foundation publishes the official Raspberry

Powers the VideoCore VI GPU and foundational silicon logic. 3. High-Speed I/O and Peripheral Buses

The schematic replaces the standard full-sized HDMI port of previous generations with two micro-HDMI ports. They are connected to independent video output blocks within the SoC, allowing dual-monitor setups up to 4K resolution at 60Hz (or dual 4K at 30Hz). 4. Wireless and Storage Interfaces

Comprehensive Guide to the Raspberry Pi 4 Model B Full Schematic For the CM4, the documentation is much more

Because the SoC operates at 3.3V/1.8V logic and HDMI utilizes 5V for the Display Data Channel (DDC), the schematic includes bidirectional level shifters to facilitate secure I2Ccap I squared cap C communication with monitors. MIPI DSI and CSI Connectors

(3V3 output)—you can quickly isolate whether the fault lies in the input polyfuse, the MxL7704 PMIC, or the SoC itself.
