A boardview file is a digital blueprint of a printed circuit board. Unlike a traditional schematic that only shows electrical symbols, a boardview shows the exact physical layout of the board. It maps out every component, pin, via, and trace.
This article provides an in-depth guide to the , offering engineers and repair technicians the necessary tools for debugging and repair. What is the CM4 94V-0 Boardview?
At its heart, the is the powerhouse of the popular Raspberry Pi 4, repackaged into a compact, flexible "system on module" (SoM). It's the brain that's designed to be embedded directly into custom hardware products. The Raspberry Pi CM4 I/O Board is a carrier board that can be used with the Compute Module 4, providing PCIe, dual HDMI, and extensive I/O.

A dead board usually indicates a short circuit on a primary voltage rail. Use the boardview search function to locate critical power entry points, such as: VIN / DC_IN (Main adapter input) +3.3V_ALWAYS / +5V_ALWAYS (Standby power rails) +1.2V_RAM / +VCC_CORE (Memory and CPU power rails) Step 3: Check Resistance to Ground

| Pin | Signal | BoardView Net Name (typical) | |-----|--------|------------------------------| | A1 | GND | GND | | A2 | 5V | VIN | | A43 | PCIe_RXN | PCIE_RXN | | A44 | PCIe_RXP | PCIE_RXP | | B45 | USB_D_P | USB_D_P | | B46 | USB_D_N | USB_D_N | | A49 | HDMI0_SCL | HDMI0_SCL | | A50 | HDMI0_SDA | HDMI0_SDA | | B10 | GND | GND |
If you are performing a component-level repair on the CM4 module itself (the small green board), look for .brd or .asc files on community sites like Schematics4u or OpenBoardView . 🔍 Step 2: Choose Your Viewer
While there is no single file titled "CM4 94V0 Boardview," the "94V-0" marking on a Raspberry Pi Compute Module 4 (CM4) indicates its UL 94V-0 flammability rating This article provides an in-depth guide to the
To save space, the CM4 does not have silk-screened component labels (like R1, C1, or U1) printed on the board. If a resistor burns up, you cannot know its value or function without a boardview.
"94V-0" is a flammability rating defined by Underwriters Laboratories (UL). It certifies that the plastic and fiberglass materials used in the PCB will self-extinguish within 10 seconds during a fire test and will not drip flaming particles.

Understanding the board layout and having access to its boardview files is essential for anyone designing custom carrier boards or performing hardware repairs on the Raspberry Pi Compute Module 4 (CM4). The CM4 represents a significant departure from previous SODIMM-style modules, utilizing two high-density 100-pin connectors for its electrical interface. Understanding the CM4 94V-0 Specification
