Description

The Waveshare Extended 4-Ch PCIe Gen 2×1 Expander is a robust solution designed to significantly increase the peripheral connectivity of embedded systems. It transforms a single PCIe channel into four independent PCIe Gen 2 x1 sockets, maintaining backward compatibility with PCIe Gen 1 x1 devices. This expansion capability is crucial for projects requiring multiple high-speed peripherals, such as those involving AI accelerators, specialized network cards, or custom industrial interfaces.

Powering the expander offers flexibility, allowing it to draw 12V directly from the PCIe slot or via an external 12V DC header. When paired with compatible boards like the Compute Module 4 PoE 4G, an external power adapter may not be necessary. The board integrates the high-performance ASMedia ASM1184 controller, ensuring stable data transmission at PCIe 2.0 speeds without the need for additional drivers, offering a plug-and-play experience for most PCIe devices.

Key Features

  • Extends one PCIe Gen 2 × 1 channel into four independent sockets.
  • Backward compatible with PCIe Gen 1 × 1 specifications for broader device support.
  • Integrated ASMedia ASM1184 controller ensures stable and efficient data flow.

Frequently Asked Questions

What is the maximum data transfer rate supported by this PCIe expander?

The Waveshare PCIe Expander supports PCIe Gen 2 x1, which provides a maximum theoretical data transfer rate of 5 GT/s (gigatransfers per second) per lane. This ensures stable and high-speed communication for compatible PCIe peripherals, significantly enhancing system throughput for demanding applications.

Is an external power supply required for the Waveshare 4-Ch PCIe Expander?

The board offers flexible power options. It can be powered directly from the 12V supplied by the host PCIe slot. Alternatively, for scenarios where the host PCIe slot cannot provide sufficient power, it can be powered via an external 12V DC header, ensuring operational stability.

Can this PCIe expander be used directly with a standard PC motherboard?

No, this expander is specifically designed for embedded systems and industrial applications, often used with SBCs like the Raspberry Pi Compute Module 4. It is not intended for direct plugging into a standard PC motherboard's PCIe slot and may not function correctly in such a configuration.

Which controller chip is used on this expansion board?

The Waveshare Extended 4-Ch PCIe Gen 2 ×1 Expander utilizes the ASMedia ASM1184 controller chip. This controller is renowned for its stable performance, reliability, and support for driver-free operation, simplifying integration into various operating systems and development environments.
