A PCIe port expander that expands one connector to 4 PCIe Gen 2 slots. It uses the ASM1184 controller, so it does not require driver installation and works immediately after connecting (plug and play). It can be powered with 12 V via the PCIe connector or 5/12 V via an external DC connector.

Intended, among others to work with CM4 IO Board expansion boards for Raspberry Pi Compute Module 4. Full documentation with examples of use is available on the product page.
