6. How to Obtain and Use the Schematic
- Visit the official Raspberry Pi hardware documentation page:
https://www.raspberrypi.com/documentation/computers/raspberry-pi.html - Download the PDF file named:
Raspberry_Pi_4_Model_B_Schematic.pdf(current revision 1.5) - Open with a PDF reader; use search for net names (e.g.,
GPIO2,USB_DP,PWR_LED). - For advanced analysis, import the PDF into vector editing software (e.g., Inkscape) or use a schematic capture tool that supports PDF import (e.g., KiCad’s PDF to schematic plugin, though manual re-drawing is often required).
