With the full schematic in hand, you can start designing your own custom projects. Here are some examples:
The official Raspberry Pi 4 Model B Reduced Schematic is the primary technical reference for the board's electrical architecture. While "Full" schematics are often restricted due to proprietary component details, the reduced version covers all major user-accessible subsystems including power, GPIO, and connectivity. Raspberry Pi 1. Power Management Unit (PMU) The heart of the Pi 4's power system is the MaxLinear MXL7704 : Receives 5V DC (3A minimum) via the USB-C connector or the 5V GPIO pins. Regulation Raspberry Pi 4 Model B Full Schematic
The power delivery circuit is one of the most complex sections of the schematic. The board uses the power management IC. Buck Converters : The With the full schematic in hand, you can
