Cm4 94v0 Boardview New 99%
The Raspberry Pi Compute Module 4 (CM4) is a high-performance system-on-module designed for industrial and embedded applications. The "94V-0" label often seen on its boardview or physical substrate indicates it meets the UL 94V-0 flammability standard, the highest rating for flame-retardant materials in electronics. Core CM4 Technical Specifications
The CM4 architecture leverages the Broadcom BCM2711 quad-core Cortex-A72 processor. Processor: Quad-core 64-bit ARM v8 at 1.5GHz.
Memory/Storage: Options range from 1GB to 8GB RAM and 0GB to 32GB eMMC flash. Connectivity:
Wireless: Optional dual-band 2.4/5.0GHz IEEE 802.11 b/g/n/ac and Bluetooth 5.0.
Ethernet: On-board Gigabit Ethernet PHY (Broadcom BCM54210PE). PCIe: One PCIe Gen 2 x1 lane. cm4 94v0 boardview new
Interfaces: Dual HDMI 2.0 (up to 4Kp60), dual MIPI CSI-2 camera ports, and dual MIPI DSI display ports.
Form Factor: Compact 55mm × 40mm board with two 100-pin high-density connectors for interface access. The 94V-0 Standard Explained
The 94V-0 designation is a safety benchmark for the PCB substrate, ensuring it can withstand high-risk environments.
Self-Extinguishing: The material must stop burning within 10 seconds of removing an ignition source. The Raspberry Pi Compute Module 4 (CM4) is
No Flaming Drips: It is prohibited from releasing flaming particles that could ignite other components.
Vertical Test (V): The rating is achieved via a vertical burn test, which is more stringent than horizontal tests because it simulates how real fires spread upward.
Thermal Stability: These boards generally handle continuous temperatures up to 130–150°C.
Overview of CM4
The Raspberry Pi Compute Module 4 (CM4) is a more compact and powerful alternative to its predecessors, featuring a quad-core Cortex-A72 CPU, supporting up to 8GB of RAM, and offering various interfaces like PCIe, USB, and more, depending on the configuration. It's designed to be used as a component in other products, similar to how one might use an SoC (System on Chip). Overview of CM4 The Raspberry Pi Compute Module
New Features and Updates
The "new" in your query might imply recent updates or features in the CM4 line. Key updates include:
- Enhanced Performance: With a more powerful CPU and the option for more RAM and storage.
- Wireless Connectivity: Some versions come with wireless connectivity options.
- Camera Interface: Support for camera interfaces has been improved.
2. Physical Hardware Review (Assuming this is a CM4 Carrier Board)
If you are looking at a generic carrier board (often found on AliExpress or eBay) labeled with these terms, here is the assessment:
The Pros:
- Compatibility: A "New" board should support the full range of CM4 modules (Lite versions without eMMC and Standard versions with eMMC).
- Standard IO: Most of these generic boards mirror the official Raspberry Pi IO Board layout. They will have:
- 2x HDMI ports (for dual displays).
- Gigabit Ethernet port (with PoE support usually).
- 2x USB 2.0 ports.
- microSD card slot (for CM4 Lite).
- PCIe Gen 2 x1 slot (often used for NVMe SSDs or WiFi cards).
- GPIO header (standard 40-pin).
- Power input (usually 12V via barrel jack).
- Build Quality: If the board is "New" and from a reputable clone manufacturer, the soldering is usually machine-done and clean. The "94V-0" rating is standard and expected.
The Cons / Watch-outs:
- Missing Silkscreen: Generic boards often lack the detailed pinout diagrams found on the official Raspberry Pi branded boards. You may need to keep a pinout diagram handy.
- PCIe Compatibility: Some cheaper generic boards have poorly designed PCIe slots. Ensure the locking mechanism works if you plan to use an NVMe drive.
- Power Supply: Ensure it comes with a power brick. Many "New" boards are sold as bare PCBs only.
