Raspberry Pi 4 Model B Full Schematic ((new)) Direct
Supports Bluetooth 5.0 and BLE. The schematic tracks a high-speed UART connection with hardware flow control pins ( CTScap C cap T cap S RTScap R cap T cap S ) dedicated to Bluetooth data transmission.
Power enters the system through a or via the 5V pins on the GPIO header. The power architecture requires a minimum of 5V/3A DC.
In previous Pi models, all USB ports and the Ethernet port shared a single USB 2.0 upstream bottleneck to the SoC. The Raspberry Pi 4 schematic resolves this by routing a single-lane Gen 2 PCI Express (PCIe x1) bus directly from the BCM2711 to a . Raspberry Pi 4 Model B Full Schematic
The board includes a Gigabit Ethernet port (enabled by a dedicated Ethernet controller) and onboard 2.4 GHz/5.0 GHz IEEE 802.11ac wireless connectivity with Bluetooth 5.0.
At the absolute center of the Raspberry Pi 4 schematic sits the System-on-Chip. Moving away from the older 28nm process used in the Pi 3, the BCM2711 is manufactured on a 28nm ruggedized process but completely overhauls its internal logic architecture. CPU Core Matrix Supports Bluetooth 5
Powers the ARM CPU cores. Voltage varies dynamically based on clock speed and CPU load.
Are you looking to design a or reverse-engineer a specific hardware fault ? The power architecture requires a minimum of 5V/3A DC
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.
Centered around the Broadcom BCM2711 SoC , a quad-core Cortex-A72 (ARM v8) 64-bit processor.
The schematic details how the BCM2711 chip breaks out into various connectivity protocols.
True Gigabit Ethernet is achieved via a dedicated RGMII (Reduced Gigabit Media Independent Interface) bus on the SoC. This connects to a Broadcom BCM54213PE Gigabit Ethernet PHY transceiver, ensuring maximum network throughput without bottlenecking the USB bus. Dual Video Output
