Waveshare Extended 4-Ch PCIe Gen 2×1 Expander | 4-Channel PCI Express Expansion Board for Compute Modules
Description
Waveshare Extended 4-Ch PCIe Gen 2×1 Expander is a dedicated 4-channel expansion board engineered for PCI Express devices. Designed with high-performance standards, the module is typically powered by a 12V power supply, though when connecting to compatible boards like the Compute Module 4 PoE series, no external power adapter is required. Featuring an advanced ASMedia controller chip, this expander guarantees stable, high-speed data transmission and requires no drivers for the adapter board itself.
Key Features
- PCIe Expansion: Extends 1-ch PCIe down into 4 independent PCIe Gen 2×1 sockets, fully compatible with PCIe Gen 1×1 devices.
- ASMedia ASM1184 Controller: Adopts a high-performance chipset that delivers significantly improved data throughput and stability over standard chips.
- Flexible Power Options: Can draw power either from the PCIe 12V interface or directly through an external 12V DC header.
- Driver-Free Design: Operates on true plug-and-play architecture for seamless integration with supported host boards.
Benefits
- Multi-Device Connectivity: Allows you to interface multiple PCI Express peripherals simultaneously to a single expansion slot.
- Optimized Signal Integrity: Premium circuit engineering ensures minimal signal loss and high-speed data transmission rates.
- Streamlined Integration: Compact layout built to fit seamlessly into specialized development board enclosures and stacks.
Applications
- Compute Module Workstations: Ideal for expanding capabilities on Raspberry Pi Compute Module carrier boards.
- Industrial & Embedded Systems: Perfect for multi-card data acquisition, custom networking, and peripheral expansion hubs.
- Advanced Prototyping: Suited for developers requiring multiple PCI Express data lanes in compact project builds.
Package Includes
- 1 x Waveshare Extended 4-Ch PCIe Gen 2×1 Expander
