This guide provides a comprehensive walkthrough of creating and understanding the critical hardware design principles for a reliable, safe, and high-performance carrier board.

Raspberry Pi provides open-access schematics for the Compute Module 4 and its official IO evaluation board. You can download the PDFs directly from the official Raspberry Pi Documentation portal: cm4 94v0 schematics

Traced through ESD protection diodes directly to the physical HDMI ports.

If using the Wi-Fi/Bluetooth enabled version (CM4xxxxxxW), you must plan for either the onboard antenna or a U.FL connector on your board, with proper clearance in the schematic.

28 GPIO pins available, supporting various functional multiplexing (PWM, SPI, I2C). Where to Find Official CM4 Schematics Can’t copy the link right now

Ensure your 5V supply is stable before the CM4 starts up.

If you are reviewing the official reference design schematic for the CM4 IO Board Go to product viewer dialog for this item.

The most reliable resource is the (CM4IO-KiCAD.zip), available on the Raspberry Pi datasheets website. This design is the definitive reference, fully tested and verified by the silicon manufacturer. It is an "industrial-grade engineering reference design with mass-production capability," perfect for hardware engineers and OEMs.
