The schematic details how the BCM2711 chip breaks out into various connectivity protocols.
: Power enters via a USB Type-C connector. The initial schematic revisions featured a design with a single pull-down resistor shared by both CC pins, causing compatibility issues with smart e-marked cables. Subsequent board revisions updated this to independent 5.1kΩ pull-down resistors on CC1 and CC2. Raspberry Pi 4 Model B Full Schematic
Designed to handle desktop-class computing tasks. The schematic details how the BCM2711 chip breaks
The Raspberry Pi 4 requires a stable 5V, 3A power source. The power subsystem on the schematic handles conversion, sequencing, and protection. Subsequent board revisions updated this to independent 5
Essential for designing enclosures, showing exact port placements and hole dimensions.
The GPU subsystem drives the dual-display capabilities. The schematic outlines the routing to two independent micro-HDMI ports, supporting up to 4K resolution at 60Hz or dual 4K displays at 30Hz.
The schematic charts two distinct HDMI blocks wired with internal ESD protection arrays and level shifters to safeguard the SoC from hot-plugging voltage spikes.
